Raman effect, change in the wavelength of light that occurs when a light beam is deflected by molecules. The phenomenon is named for Sir Chandrasekhara Venkata Raman, who discovered it in 1928. When a beam of light traverses a dust-free, transparent sample of a chemical compound, a small fraction of the light emerges in directions other than that of the incident (incoming) beam. Most of this scattered light is of unchanged wavelength. A small part, however, has wavelengths different from that of the incident light; its presence is a result of the Raman effect.

In 1928, Sir C.V. Raman change the wavelength of light when the light beam is deflected by molecules. This day make the discovery of Raman effect of Indian Physicist in February 28, 1928.

He got Nobel prize for that invention.

What is mean by 'Raman Effect'?

He got the Nobel prize in Physics.
