Long Essay on CV Raman 500 Words in English

Below we have given a long essay on CV Raman of 500 words is helpful for classes 7, 8, 9 and 10 and Competitive Exam Aspirants. This long essay on the topic is suitable for students of class 7 to class 10, and also for competitive exam aspirants.

Born at Trichinopoly in Tamil Nadu on 7th November, 1888, his father was a lecturer in Mathematics and Physics, in Mrs AV Narasimha Rao College, Visakhapatnam, and later joined Presidency College, Madras. His maternal grandfather was a Sanskrit scholar, well versed in ‘navya nyaya’ or modern logic.

So, from an early age, he was immersed in an academic atmosphere. He was a diligent student. He entered the Presidency College, Madras, in 1902, and in 1904 passed his BA examination, winning the first place and a gold medal in Physics. In 1907, he gained his MA degree, obtaining the highest distinctions. His earliest researches in optics and acoustics—the two fields of investigation to which he dedicated his entire career were carried out while he was a student. Since at that time a scientific career did not appear to offer the best possibilities, Raman joined the Indian Finance Department in 1907. Though the duties of his office took most of his time, Raman found opportunities for carrying on experimental researches in the laboratory of the Indian Association for the Cultivation of Sciences at Calcutta.

In 1917, he was offered the newly endowed Palit Chair of Physics at Calcutta University, and decided to accept it. Raman’s main research was focussed on acoustics and musical instruments, and led to his election as fellow of the Royal Society in 1924. It was during a trip to England in 1921 that he was fascinated by the blue colour of the Mediterranean.

With a very simple experiment, he convinced himself that the blue colour of the sea was not only due to the reflection of the sky, as proposed by Lord Rayleigh, but mainly due to the scattering of light by water molecules. On his return to Calcutta, he began a systematic study of the scattering of light by different liquids, culminating in the discovery of a totally new kind of radiation, predicted by the quantum theory and named after him.

There Raman radiations carry vital information about the internal structure of the scattering molecules, and have proved to be of immense importance in studying molecular structures. His efforts finally paid off when he was awarded the Nobel Prize in Physics in 1930, the first to be ever won by an Indian. Thereafter, he became the Honorary Secretary of the Indian Association for the Cultivation of Sciences. After 15 years in Calcutta, he became Professor at the Indian Institute of Science at Bangalore (1933-1948) and in 1948, he became the Director of the Raman Institute of Research at Bangalore, established and endowed by himself. He also founded the Indian Journal of Physics in 1926, of which he was the Editor.

Raman sponsored the establishment of the Indian Academy of Sciences and served as its President since its inception. He was also the President of the Current Science Association, Bangalore, which publishes Current Science. (India)

Raman has done credible work in his field and his early memoirs appeared as Bulletins of the Indian Association for the Cultivation of Sciences. These dealt with the maintenance of vibrations and the theory of musical instruments of the violin family. In 1922, he published his work on the ‘Molecular Diffraction of Light’, the first of a series of investigations with his collaborators which ultimately led to the discovery, on 28th February, 1928, of the radiation effect, which is named after him. This work bagged him the 1930 Nobel Prize in Physics.

Some other investigations which propelled the world of science during his time were the experimental and the theoretical studies on the diffraction of light by acoustic waves of Ultrasonic and Hypersonic frequencies. In 1932, he and Suri Bhagavantam discovered quantum photon spin. During his term at IISc, he admitted the talented electrical engineering student, GN Ramachandran, who went on to become a recognised X-ray crystallographer.

Short Essay on CV Raman 200 Words in English

Below we have given a short essay on CV Raman is for Classes 1, 2, 3, 4, 5 and 6. This short essay on the topic is suitable for students of class 6 and below.

In 1948, Raman, through studying the spectroscopic behaviour of crystals, approached fundamental problems of crystal dynamics in a new manner. His laboratory has been dealing with the structures and properties of diamond, the structure of optical behaviour of numerous iridescent substances like opal and pearls.

This luminous star in the firmament of the scientific fraternity has been honoured with a large number of honorary doctorates and memberships of scientific societies. He was elected as a fellow of the Royal Society in 1924 and knighted in 1929. In 1941, he was awarded the Franklin Medal. In 1954, he was conferred upon, the Bharat Ratna. He got the Lenin Peace Prize in 1957.

Another big honour was that the American Chemical Society and IACS recognised his discovery as an International Historic Chemical Landmark. India celebrates National Science Day every year on 28th February to remember the discovery of Raman effect that took place in 1928.

At the end of October, 1970, he collapsed in his laboratory. Doctors gave him four hours to live. He survived and asked to be shifted from the hospital to the gardens of his institute. He passed away on 21 st November, 1970. His life was a testimony to hard work, patience and perseverance for achieving one’s goals. One should also be level headed and not go overboard on attaining success. With him, dawned an era of high quality science, and he showed the light for others to follow.

Essay On C V Raman – 10 Lines, Short and Long Essay For Children & Students

Since his father taught physics and mathematics at AV Narasimha Rao College in Visakhapatnam, CV Raman was raised in an academic environment. Raman was a dedicated student. He enrolled in the Presidency College in Madras in 1902, and in 1904 he successfully completed his BA programme, earning first place and a gold medal in Physics. He received the highest honours when he earned his MA in 1907. His early studies in optics and acoustics—the two areas of study to which he devoted his whole professional life—were conducted while he was still a student. Raman's primary study was on musical instruments and acoustics, which helped him be elected as a fellow of the Royal Society in 1924.

Early Life | C. V. Raman was born in Madras Province, India on November 7, 1888 in Thiruvanaikoil, Tiruchirappalli. His full name was Chandrasekhara Venkata Raman. He was the son of Parvati Ammal and R. Chandrasekhara Ver. His father taught physics and mathematics at Presidency College in Madras. His early studies in optics and acoustics were conducted while he was still a student. Raman began working for the Indian Finance Department in 1907 after finding that a scientific career did not appear to give the best opportunities at the time. Raman found opportunities to do experimental research in the lab of the Indian Association for the Cultivation of Sciences in Calcutta, despite his office duties consuming the majority of his time.

Accomplishments | The advancement of science in India was influenced by the work of Indian physicist C. V. Raman. In 1930, he became the first Indian scientist to receive the prestigious Nobel Prize in Physics. His discovery is commonly referred to as the "Raman effect" or "Raman scattering," which is the inelastic scattering of a photon. He received numerous honorary doctorates and memberships in prestigious scientific institutions. He passed away in Bangalore on November 21, 1970, at the age of 82. In India, National Science Day is observed on February 28 every year to commemorate the day that Indian scientist Sir Chandrasekhara Venkata Raman discovered the Raman phenomenon.

CV Raman was the first Indian and Asian to be awarded the Physics Nobel Prize. Most importantly, he accomplished this while India was not well-known in the scientific community.

The Raman Effect

In 1928, while researching how light refracts in different materials, he discovered that when a transparent substance is lit by a beam of light of a particular frequency, a small amount of the light exits at right angles to the original direction, some of which is of a different frequency from the incident light. The energies connected to changes in rotational and vibrational states in the scattering material were named as Raman frequencies. In short, the Raman effect, discovered by C.V. Raman, occurs when light that shines through a material is scattered and its wavelength varies from that of the original incident light due to interactions with the molecules in the substance.

Academic Contribution

Raman received his knighthood in 1929, and in 1933 he relocated to the Indian Institute of Science in Bangalore to take over the physics department. He was appointed the Raman Research Institute's director there in 1947, and in 1961 he was elected a member of the Pontifical Academy of Science. He helped establish almost all Indian research institutions during his lifetime, founded the Indian Journal of Physics and the Indian Academy of Sciences, and mentored hundreds of students who went on to hold significant positions in academic institutions and government in India and Myanmar (Burma).

His Work and Achievements

After spending 15 years in Calcutta, he moved to Bangalore to work as a professor at the Indian Institute of Science (1933–1948), and in 1948 he was appointed director of the Raman Institute of Research, which he had founded and endowed. The Indian Association for the Cultivation of Sciences appointed him as Honorary Secretary. In 1926, he also started the Indian Journal of Physics, serving as its Editor. Raman supported the creation of the Indian Academy of Sciences and presided over it. He also served as the president of the Bangalore Current Science Association. Raman had produced credible work in his discipline, and the Indian Association for the Cultivation of Sciences published his early autobiographies. These addressed the maintenance of vibrations and the theory of violin-family musical instruments. He presented a paper on the "Molecular Diffraction of Light" in 1922, marking the beginning of a series of studies with his associates that eventually resulted in the discovery of the radiation effect, which bears his name. He won the 1930 Nobel Prize in Physics for this work. He and Suri Bhagavantam made the quantum photon spin discovery in 1932.

Raman lost consciousness in his lab at the end of October 1970. He pulled through and requested to be moved from the hospital to his institute's grounds. On November 21st, 1970, he passed away. His life served as an example of how hard work, dedication, and patience can lead to success. A new era of higher science began with him, and he set the example for others to follow.

c v raman essay writing competition

At a time of distress when the entire nation was struggling to be free from the shackles of oppression and cruelty, a man of science was busy making space for India on the globe.

“Look at the resplendent colours on the soap bubbles! Why is the sea blue? What makes diamond glitter? Ask the right questions, and nature will open the doors to her secrets.”

These are the words of Sir Chandrasekhara Venkata Raman, also known as Sir C V Raman, whose inquisitiveness and incessant efforts to find the answers made him the first Asian physicist to receive the Nobel prize in 1930. 7th November marks the birth anniversary of this revered scientist who discovered the Raman Effect. His discovery enabled the scientific community to move forward and better understand various natural phenomena.

Sir C V Raman was born in 1888 in Tiruchirappalli, Tamil Nadu. His father was Chandrashekhar Ramanathan. He was a lecturer of Mathematics and Physics at the Presidency College at the University of Madras. He graduated at the age of 16 from the same college. He was a brilliant student and a gold medalist. After obtaining Masters' in Physics, he secured a government job in Indian Finance Department. He continued experimental research in acoustics and optics in the laboratory of the Indian Association for the Cultivation of Science (IACS). He also published his work in leading Physics journals.

In 1917, he left his government job and became a Palit Professor of Physics at the University of Calcutta. He continued studying acoustics, the sounds of stringed instruments like violin and veena and percussion instruments like tabla and mridangam. His work earned him a good reputation among his peers in the country and internationally. On his first trip to London in 1921, he received a warm welcome from English Physicists J. J. Thomson and Lord Rutherford.

While returning to India from London via sea route, the blue colour of the sea caught his attention. Dissatisfied with Lord Railey’s explanation that the colour of the sea was blue due to the reflection of the colour of the sky, he decided to investigate the reason behind it. With his mentee K. S. Krishnan , he started studying light scattering.

His sincerity, dedication, and contribution towards the discipline of physics got recognition from the Royal Society of London when he was elected a fellow of the society in 1924. He got invited to the California Institute of Technology (Caltech) in the United States by Nobel Laureate Robert Millikan, where he spent four months studying the scattering of light. On 28th February 1928, he finally got his answer when he discovered Raman Effect, according to which the light changes its wavelength and frequency when it gets deflected by molecules. The day has been commemorated as National Science Day every year since 1987

Sir Raman was already a renowned name in the field of science but discovering the Raman effect strengthened his position in the community. He received a knighthood from the Royal Society of London in 1929, and the following year he became the first Indian scientist to be honoured with the Nobel Prize. He also headed the Indian Institute of Science (IISc), Bangalore as the first Indian director.

Sir Raman was educated in India; he did most of his research work here and went on to earn the reputation of an internationally celebrated physicist. Ernest Rutherford, who discovered the nucleus, referred to Raman’s Spectroscopy in his presidential address to the Royal Society of London.

Sir Raman dreamt of building a society in India like the Royal Society of London and other entities in the world to inculcate scientific temperament in the Indian youth. In 1934 he founded the Indian Academy of Science (IAS) in Bangalore to further the cause of science. After retiring from IISc, Sir Raman founded Raman Research Institute (RRI) to continue his research. He remained the director of RRI until his death on 21st November 1970.

He expressed his disappointment in Indian talent leaving the country to find better opportunities abroad when he said:

“My life has been an utter failure. I thought I would try to build true science in this country, but all we have is a legion of camp followers for the west.”

But he remained open to working with western physicists like Max Born and Erwin Schrodinger, both of who were Nobel Laureates. He persuaded German scientist Max Born to come to India and work for the country. He stayed for some time at IISc, but Sir Raman’s efforts to prolong his stay could not fructify.

Sir C. V. Raman was honoured on numerous platforms for his incredible contribution to advancing the sciences. After India became independent, he became the first national professor of India. He was awarded Bharat Ratna in 1954. He remains one of the few recipients to receive both the Bharat Ratna and the Nobel Prize. He received Lenin Peace Prize in 1957 in Kremlin. Several buildings and roads are also named after him in Russia.

Today, the Raman effect is used in medicine, surgery, and medical diagnosis like cancer detection. It is being used in remote sensing, geology, and mineralogy. It is used for ensuring quality control in the pharmaceutical industry. Police are also using it for forensic work. The most visible public use of Raman spectroscopy can be seen at airports, metro stations, malls, or other places of security where scanners are used to detect explosives and drugs.

Sir C. V. Raman’s discovery has proved to be a significant stepping stone to the world of science. He left us half a century ago, and his discovery will also be a century old in a few years. Still, his ideas will always remain relevant and encourage curious minds to unravel the secrets of nature.

ADVERTISEMENTS:

Read this comprehensive essay on Chandrasekhar Venkata Raman (1888 A.D. – 1970 A.D.) !

The Great Indian physicist Chandrasekhar Venkata Raman, popularly known as C.V Raman, was born on 7 th November, 1888 at Trichirapalli in Tamil Nadu. His father was a physics teacher and so it was natural that Raman developed love for this subject. He was a brilliant student from the very beginning. As a brilliant and promising lad, he passed his matriculation examination at the young age of 12 from Madras University.

His parents wanted to sent him England for higher studies but his poor health did not allow it. He studied at Hindu College, Visakhapatnam and Presidency College, Madras. He obtained his post-graduation degree in physics in 1907 with the top position. During his student period he conducted many researches and published his papers in many reputed magazines.

Chandrasekhar Venkata Raman

His interest in physics was deep and lasting and so he continued his research work in his spare time in the laboratory of the Association. He published his research results in the leading journals of Calcutta, now Kolkata which were in regard to the subject of propagation of light. These original research papers were of great scientific significance.

When these came to the notice of the then Vice -Challenger of Calcutta University, Sir Ashutosh Mukharjee, he appointed him Professor of physics in the University. During his stay at the University he continued his research with much more devotion and won immense honour and recognition as a physicist.

He was elected the Fellow of the Royal Society of London in 1924. He discovered the “Raman Effect” in 1928. For it he was awarded the Nobel Prize for Physics in 1930. He became the first Indian to win this prestigious honour. With this award, his reputation increased by leaps and bounds and many Universities and institutions of repute honoured him with Ph D and D.Sc. degrees.

In December, 1927 he was busy in laboratory when the news came that the well-known physicist A.M. Compton was awarded the Nobel Prize for demonstrating that the nature of X-rays undergoes a change when passed through a matter.

This effect came to be known as the “Compton Effect.” Encouraged by this discovery, Raman continued his experiments and ultimately proved that light rays can also be scattered. His discovery enabled for the first time, the mapping of possible levels of energy gains of molecules and atoms of a substance and thus discovered their molecules and atomic structure. This discovery of the scattering of light led to the development of a simple alternative to infra-red spectroscopy, namely, Raman Spectroscopy.

Raman Effect happens when molecules of a medium scatter light energy particles known as photons. The spectrum varies with the nature of the transparent medium used to scatter the light. Raman Effect has proved to be of great scientific value and with its help the structure of more than 200 compounds has been known. He also gave us the scientific explanation for the blue colour of the sky and the ocean.

He explained that the blue color of the ocean was as a result of the scattering of sunlight by the molecules of the water. He travelled widely abroad delivering lectures about his discoveries and researches. In 1933 he became the Director of the Indian Institute of Sciences, Bangalore. In 1943 he founded the Raman Research Institute at Bangalore. He was knighted in 1927. He was awarded the Bharat Ratna in 1954 and the International Lenin Prize in 1957.

Raman was a born genius and a self-made man and scientist with deep religious convictions. His interests were wide and deep and so were his contributions to the human knowledge and development. Besides optics, he was deeply interested in acoustics—the science and study of sound.

His contributions to the mechanical theory of bowed, stringed and other musical instruments like violin, sitar, cello, piano, veena, Tanpura and mridangam have been very significant. He explained in detail how these musical instruments produce harmonious tones and notes. He died on November 21, 1970 at the ripe age of 82 at Bangalore and his mortal remains were consigned to flames in the campus of the Raman Research Institute.

C.V. Raman was an Indian physicist who won the Nobel Prize for Physics in 1930 for his discovery of what became known as the Raman effect . He significantly influenced the growth of science in India through his teaching, his support of nearly every Indian research institution of his time, and his founding of the Indian Academy of Sciences.

What did C.V. Raman discover?

C.V. Raman discovered the Raman effect , which occurs when light that shines through a material is scattered and its wavelength changes from that of the original incident light because of its interactions with the molecules in the material.

Why did C.V. Raman win the Nobel Prize?

C.V. Raman was awarded the 1930 Nobel Prize in Physics for his discovery of the Raman effect , in which light that passes through a material is scattered and the wavelength of the scattered light is changed because it has caused an energy state transition in the material’s molecules .

C.V. Raman (born November 7, 1888, Trichinopoly , India—died November 21, 1970, Bangalore) was an Indian physicist whose work was influential in the growth of science in India . He was the recipient of the Nobel Prize for Physics in 1930 for the discovery that when light traverses a transparent material, some of the light that is deflected changes in wavelength. This phenomenon is now called Raman scattering and is the result of the Raman effect .

After earning a master’s degree in physics at Presidency College, University of Madras , in 1907, Raman became an accountant in the finance department of the Indian government. He became professor of physics at the University of Calcutta in 1917. Studying the scattering of light in various substances, in 1928 he found that when a transparent substance is illuminated by a beam of light of one frequency, a small portion of the light emerges at right angles to the original direction, and some of this light is of different frequencies than that of the incident light. These so-called Raman frequencies are the energies associated with transitions between different rotational and vibrational states in the scattering material.

Raman was knighted in 1929, and in 1933 he moved to the Indian Institute of Science, at Bangalore , as head of the department of physics. In 1947 he was named director of the Raman Research Institute there and in 1961 became a member of the Pontifical Academy of Science. He contributed to the building up of nearly every Indian research institution in his time, founded the Indian Journal of Physics and the Indian Academy of Sciences, and trained hundreds of students who found important posts in universities and government in India and Myanmar (Burma). He was the uncle of Subrahmanyan Chandrasekhar , who won the 1983 Nobel Prize for Physics, with William Fowler .

Long Essay on CV Raman 500 Words in English

Below we have given a long essay on CV Raman of 500 words is helpful for classes 7, 8, 9 and 10 and Competitive Exam Aspirants. This long essay on the topic is suitable for students of class 7 to class 10, and also for competitive exam aspirants.

Born at Trichinopoly in Tamil Nadu on 7th November, 1888, his father was a lecturer in Mathematics and Physics, in Mrs AV Narasimha Rao College, Visakhapatnam, and later joined Presidency College, Madras. His maternal grandfather was a Sanskrit scholar, well versed in ‘navya nyaya’ or modern logic.

So, from an early age, he was immersed in an academic atmosphere. He was a diligent student. He entered the Presidency College, Madras, in 1902, and in 1904 passed his BA examination, winning the first place and a gold medal in Physics. In 1907, he gained his MA degree, obtaining the highest distinctions. His earliest researches in optics and acoustics—the two fields of investigation to which he dedicated his entire career were carried out while he was a student. Since at that time a scientific career did not appear to offer the best possibilities, Raman joined the Indian Finance Department in 1907. Though the duties of his office took most of his time, Raman found opportunities for carrying on experimental researches in the laboratory of the Indian Association for the Cultivation of Sciences at Calcutta.

In 1917, he was offered the newly endowed Palit Chair of Physics at Calcutta University, and decided to accept it. Raman’s main research was focussed on acoustics and musical instruments, and led to his election as fellow of the Royal Society in 1924. It was during a trip to England in 1921 that he was fascinated by the blue colour of the Mediterranean.

With a very simple experiment, he convinced himself that the blue colour of the sea was not only due to the reflection of the sky, as proposed by Lord Rayleigh, but mainly due to the scattering of light by water molecules. On his return to Calcutta, he began a systematic study of the scattering of light by different liquids, culminating in the discovery of a totally new kind of radiation, predicted by the quantum theory and named after him.

There Raman radiations carry vital information about the internal structure of the scattering molecules, and have proved to be of immense importance in studying molecular structures. His efforts finally paid off when he was awarded the Nobel Prize in Physics in 1930, the first to be ever won by an Indian. Thereafter, he became the Honorary Secretary of the Indian Association for the Cultivation of Sciences. After 15 years in Calcutta, he became Professor at the Indian Institute of Science at Bangalore (1933-1948) and in 1948, he became the Director of the Raman Institute of Research at Bangalore, established and endowed by himself. He also founded the Indian Journal of Physics in 1926, of which he was the Editor.

Raman sponsored the establishment of the Indian Academy of Sciences and served as its President since its inception. He was also the President of the Current Science Association, Bangalore, which publishes Current Science. (India)

Raman has done credible work in his field and his early memoirs appeared as Bulletins of the Indian Association for the Cultivation of Sciences. These dealt with the maintenance of vibrations and the theory of musical instruments of the violin family. In 1922, he published his work on the ‘Molecular Diffraction of Light’, the first of a series of investigations with his collaborators which ultimately led to the discovery, on 28th February, 1928, of the radiation effect, which is named after him. This work bagged him the 1930 Nobel Prize in Physics.

Some other investigations which propelled the world of science during his time were the experimental and the theoretical studies on the diffraction of light by acoustic waves of Ultrasonic and Hypersonic frequencies. In 1932, he and Suri Bhagavantam discovered quantum photon spin. During his term at IISc, he admitted the talented electrical engineering student, GN Ramachandran, who went on to become a recognised X-ray crystallographer.

Below we have given a short essay on CV Raman is for Classes 1, 2, 3, 4, 5 and 6. This short essay on the topic is suitable for students of class 6 and below.

In 1948, Raman, through studying the spectroscopic behaviour of crystals, approached fundamental problems of crystal dynamics in a new manner. His laboratory has been dealing with the structures and properties of diamond, the structure of optical behaviour of numerous iridescent substances like opal and pearls.

This luminous star in the firmament of the scientific fraternity has been honoured with a large number of honorary doctorates and memberships of scientific societies. He was elected as a fellow of the Royal Society in 1924 and knighted in 1929. In 1941, he was awarded the Franklin Medal. In 1954, he was conferred upon, the Bharat Ratna. He got the Lenin Peace Prize in 1957.

Another big honour was that the American Chemical Society and IACS recognised his discovery as an International Historic Chemical Landmark. India celebrates National Science Day every year on 28th February to remember the discovery of Raman effect that took place in 1928.
