Early Life

Chandrashekhar Venkataraman was born on 6 November 14 AD in a place called Tiruchirapalli in Tamil Nadu. Your father Chandrashekhar Iyer S. P. G. He was a professor of Physics in the college. Your mother Parvati Ammal was a woman from a cultured family. In 1792 AD, your father Chandrashekhar Iyer, Mrs. A.K. of Visakhapatnam. Vn He went to college as a professor of Physics and Mathematics. At that time, you were four years old. He did his primary education in Visakhapatnam. The natural beauty and scholarly association there particularly impressed you.

In those days, there was no facility for a genius like you to become a scientist. Therefore, you sat in the competition of the Finance Department of the Government of India. He also came first in the competition examination and in June 1906, he went to Calcutta as Assistant Accountant General. At that time it seemed that stability has come in your life. You will get a good salary and become an accountant general. Will receive high pension in old age.

But you were returning from office one day and saw a sign board which read ‘Indian Council for Scientific Studies (Indian Association for Cultivation of Science)’. As if you have touched the electric current. Then you got off the tram and reached the council office. Having reached there, he introduced himself and got permission to experiment in the council’s laboratory.

Raman quit his government job in the year 1917 and accepted Palit Chair in Physics under the Indian Association for Cultivation of Science. In 1917, he was appointed as Professor of Physics of the University of Calcutta. In 1924 Raman was made a member of the ‘Royal Society of London’ for his contribution in the field of ‘Opticus’ and this is very much for any scientist. It was a matter of honor.

The Raman effect was discovered on 28 February 1928. Raman announced it in the foreign press the very next day. He was published by the prestigious scientific journal Nature. On 16 March 1928, he gave a speech at the South Indian Signs Association, Bangalore, on top of his new discovery. After this, gradually the Raman effect began to be explored in all the laboratories of the world.

Scientific Life

In 1909, J.D. N. Tata established the Indian Institute of Science in Bangalore to develop scientific talent in India. The Mysore King provided 150 hectares of land for this institution. The construction of the institute started with the confidence of the British rule. On completion of the construction work, the British government appointed its director there. The members of the institution were also English.

In 1933, Venkatraman became the first Indian director of the Indian Institute of Science. At that time a lot of money was being spent in the name of the institute. But the development of scientific talent was negligible. In this situation, C. V. Raman disseminated that tradition of British propagation of science throughout the country. He made a very creative change in the policies and programs of the institution. By doing this, they wanted to improve that institution. He gave birth to greenery at the Indian Institute of Science. Flowering plants were also grown there. Later, this institute became a major center of attraction. Chandrashekhar Venkataraman Biography

Why are Europe and America superior in scientific talent? Why are Indian scientific talents not the best? These questions were always rotating in Raman’s mind. To awaken India in the field of science, he awakened the youth of the country to science. For this, Raman had to address various meetings in many metros of the country. His speech inspired many young people. Due to which Vikram Sarabhai, Homi Jehangir Bhabha and K.R. Young scientists like Ramanathan have brought laurels to themselves and their country throughout the world.

A few days later Raman wrote another research paper and sent it to the internationally acclaimed journal ‘Nature’ in London. By that time, the confidence to search freely on scientific subjects had developed in them. Ramon wrote a letter to Lord Rayleigh, a respected and noted scientist of the time. In this letter he asked Lord Rayleigh some questions about his scientific discoveries. Lord Raylew addressed those questions to the professor. He could not even imagine that an Indian teenager is directing all these scientific discoveries.Chandrashekhar Venkataraman Biography

Raman would reach the council’s laboratory at five and a half in the morning and come in at ten o’clock to get ready for office. Five o’clock in the evening after office and reach the laboratory work there until ten o’clock at night. Even on Sundays, he would be busy with his experiments in the laboratory all day. This was his routine for years. Raman’s research at that time was limited to musical instruments. The theme of his discovery was why melodious vocals come out of such instruments as veena, violin, mridang and tabla.

In his research, Raman also took the help of Ashutosh Dey, an ordinary member of the council. He had made Dey so masterful of scientific research methods that Dey began to write the results of his own discoveries, which were later published in famous science journals. Ramon believed in those who wanted to learn rather than those who were only trained or educated. Chandrashekhar Venkataraman Biography

In fact, he quickly formed a team of young scientists who assisted in his experiments. He also started giving speeches in the hall of the council to make science popular, so that young people can be introduced to new developments in science. He became the spokesperson for science in the country. Ashutosh Mukherjee, Vice Chancellor of the University of Calcutta, who was called the ‘tiger of Bagal’, was greatly impressed by Raman’s dedication and work in science.

Sir Raman established the Raman Research Institute near Bangalore in 1943. In this institution, he continued his experiments till the end of his life and kept studying. This great Indian and scientist died in 1970. We all take great pride in the works and achievements of Sir Raman. He was a great physicist and scientist as well as a great human being. Pride and greed could not even touch them. They continued to search for the eternal truth and found it.

In 1921, Venkataraman received an invitation from Oxford, England to attend the University Congress. There he met Lord Rutherford, J. J. World famous scientists like Thomson. An unexpected incident while returning to India from England (which is described at the beginning of this article) prompted the discovery of the ‘Raman effect’. Actually, Venkataraman reached his colleague Dr. K. s. Together with Krishnan, he conducted several experiments on the scattering of light over transparent blocks of water and ice and other earth objects.

After all the experiments Venkataraman reached his discovery, which is famous by the name ‘Raman effect’. You might be wondering what is this Raman effect and how much effect does it have in the world of physics? According to the Raman effect, when one-wave light (light of the same frequency) is passed through different chemical fluids, the wavelength of a microscopic part of the light is different from the wavelength of the original light. This variation in wave-length is due to the exchange of energy.

When there is a decrease in energy, the wavelength becomes longer and when the energy increases, the wavelength decreases. This energy is always decreasing in a certain amount and hence the change in wave-length is always in a fixed amount. Actually, the rays of light are made up of innumerable microscopic particles, these particles are called photons.

By the way, we know that light has dual nature, it also behaves like waves and also like particles (photons). The Raman effect has particularly helped in understanding the internal atomic structure of energy of photons. The Raman spectrum can be obtained by passing the same frequency light in any transparent fluid.Chandrashekhar Venkataraman Biography
