RAMAN EFFECT

The discovery of Raman Effect was not accident, but was a result of prolonged and patient research extending over a period of nearly seven years. These researches began in the summer of 1921. When, during the voyage made on the occasion of his first visit to Europe, Raman’s attention was attracted to the beautiful blue colour exhibited by the water of the deep sea. On his return to India, he started a series of experimental and theoretical studies on scattering of light by the molecules of transparent media such as air water or ice and quartz. The experiment of Professor Raman revealed that the scattered light is different from the incident. This led to the discovery of a new effect. For his investigation on the scattering of light and the discovery of the effect known after him, Raman Effect, Nobel Prize was awarded to him in 1930.
