C V Raman

India : Nobel Laureate Physicist

Birth :1888        Death : 1970

Dr.Chandra Shekhar Venkat Raman is one of the most distinguished scientists of the 20th century. His discovery known as the `Raman Effect’ made a very distinctive contribution to physics. For this discovery, he was awarded the Nobel Prize in Physics in 1930. He was the first Indian Scientist and also the first Asian to receive a Nobel Prize in Physics. This discovery of Raman is significant for one more reason. C.V. Raman studied and conducted his scientific researches living in India while there was the widely shared notion that no great scientific discovery could be made under the then existing scientific facilities in India. The scientific talent of Raman appeared at a very young age. His first Research paper, “The unsymmetrical diffraction bands due to a rectangular aperture” was published in London’s Philosophical Magazine when he was only 18. This research made Raman famous in world’s scientific circles. Later on, he made many important discoveries in light, sound and magnetism.

Dr. C.V. Raman was born on 7th November, 1888 in Tirchurappalli (Tamil Nadu). His father’s name was Chandra Shekhar Aiyer who had special interest in science and mathematics. His mother Parvati was a cultured lady. Raman was very intelligent since his early childhood. lie passed his matriculation when he was only 12. In 1904, when he was only 16, he passed his B.A. from the Presidency College, Madras, and was the only student to get a first class. He did his M.A. in Physics from the same college and broke all previous records. Then he appeared a competitive examination of the Finance Department (Accountant General) in Calcutta, but he was interested in scientific researches. Prof. Ashutosh Mukherjee, then Vice Chancellor of Calcutta University offered him a teaching post. Raman left his highly paid government job to become a Professor of science. In 1914, a science college was established in Calcutta and Raman was appointed its Principal. In 1921, he was awarded the degree of ‘Doctor of Science’ by the Calcutta University and in 1924, he was elected a Fellow of the Royal Society of London. In 1928, Raman was elected President of the Indian Science Congress and in 1929, the British government in India conferred on him the title of ‘Sir’. From 1933 to 1948, he was the Director of Indian  Institute of Science, Bangalore.

Meanwhile he continued to carry out different types of experiments and researches on the sun rays passing through water, transparent ice blocks and other media. For these experiments, Raman used a mercury arc and a spectograph. Raman obtained some new lines in the; spectrum on passing the sun rays through different substances. These lines were later called ‘Raman Lines’ and this discovery the ‘Raman Effect’. For this discovery he was awarded the Nobel Prize in Physics in help in the industrial development of the world. The government of India the same discovery. This discovery of Raman rendered the most valuable 1930. The Royal Society of London also awarded him `Hume Medal’ for also honoured him with the highest honour of the country ‘Bharat Ratna’ in 1954. Dr. C.V. Raman led a simple life. He passed away in Bangalore on 21 November, 1970.

CV RAMAN: THE GREAT INDIAN PHYSICIST

 Sir CV. Raman, created history when he became the first ever-Indian scientist to win the highest award in science, the Noble prize for physics in the year 1930. His major work known as the ‘Raman Effect’ evokes as much scientific interest today as it did at the time of its discovery. Raman was known for his scientific temperament and boundless curiosity. He was loved! as a teacher and his efforts on scientific research provided a foundation   for   scientific   inquiry   and experimentation in the country.

Chandrasekhar Venkata Raman or CV Raman was born in Thiruchinapalli, in Tamil Nadu, India on 7 November 1888. He was the son of Chandrasekhar Iyer and Parvathi Ammal. His father was an academician. Raman spent his early years in Vishakhapatnam where his father taught mathematics at the Mrs. AVN College.

Raman showed himself to be an academic genius by achieving great learning at a very young age. By the time he was eleven, he had already completed his secondary school education. At fifteen, he topped his class and passed out from the prestigious Presidency College in Madras (now Chennai) in B.A.Honors in Physics and English. He continued to study at the Presidency College and topped his class once more in 1907 in M.A. honors even before the completion of his seventeenth birthday.

After the completion of his studies, Raman got married to Lokasundari and was compelled to take up work as an Assistant Accountant General with the Indian Civil Services in Kolkata since there were no other opportunities existing for him as a scientist. Even while working as an accountant, Raman continued to experiment with physics in the laboratories of the Indian Association for the Cultivation of Science whenever he found the time. He studied the physics of Indian musical instruments.

Raman’s dedication to science gained him a reputation and he was offered the position of Sir Taraknath Palit Professorship of Physics at Calcutta University in the year 1917. In the next fifteen years, that he spent there, he conducted in-depth research and study on optics and the scattering of lights and discovered the phenomenon that is today known as the ‘The Raman Effect’.

Raman announced his discovery on the 16th of March 1928 at the joint meeting of the South Indian Science Association and the Science Club of Central College held in Bangaluru. The Raman Effect confirmed that light was made up of particles known as ‘photons’. The discovery attracted worldwide attention of physics researchers. About 1800 research papers were published on the effect in the first twelve years of its discovery. The discovery helped in the study of the molecular and crystal structures of different substances.

His brilliant career in science won him much recognition and several prestigious awards. In 1924, he was elected to the Royal Society of London. In 1929, after the announcement of his discovery, the British made him a knight of the British Empire. In 1930, not only was he honored with the prestigious Hughes medal from the Royal Society but he was also awarded with the most sought after prize in science, the Noble Prize in Physics, making the nation proud of him. Later, the Government of India honoured him with the highest award in the country, the ‘Bharat Ratna’ award.

Raman went on to establish the foundation of scientific research in India. He became the first director of the Indian Institute of Sciences in Bangalore that was established in 1934. He went on to teach physics at the institute. In 1947, after India gained independence, the new government appointed him as the first National Professor.

After his retirement from the Indian Institute in 1948, he went on to establish his own research institute called the Raman Research Institute in Bangalore and served the cause of science by acting as its director until his death on 21 November 1970. During his entire teaching career, he was immensely loved and respected by his students for his inspiring lectures and devotion to the subject of physics.
