Raman-Effect


                                                                    C V Raman (1888-1970)


Sri Chandrasekhara Venkata Raman FRS was an Indian Physicist known for his work in the field of Light Scattering.

Light is scattered by several substances. The nature of the scattered light was analyzed by Lord Raleigh and to explain the phenomenon he developed the theory of 'elastic scattering of light'. In this theory there is no provision for a change in the frequency of the light wave due to scattering A.H.Compton while studying the scattering of X-rays by electrons found a change in the frequency of electrons scattered. C.V.Raman,

(1888-1970) who was working at the laboratories of the Indian Association for the Cultivation of Science, Culcutta studied the light scattering by molecules. Although the possibility of a change in frequencies of light waves due to scattering was predicted by Heisenburg and Smeckal, most scientists held the view that there is only a remote possibility of anyone detecting such a change. Raman succeeded in detecting the phenomenon, with the help of a simple apparatus, and this became famous as "Raman Effect". Raman was awarded Nobel Prize in 1930 for his discovery.
