C.V.Raman awarded Nobel Prize for scattering of light in 1954.

C.V Raman was the famous Indian physician who discovered scattering of light.

When photons are scattered from an atom or molecule, most photons are elastically scattered (Rayleigh scattering) , such that the scattered photons have the same energy (frequency and wavelength) as the incident photons. A small fraction of the scattered photons (approximately 1 in 10 million) are scattered by an excitation, with the scattered photons having a frequency different from, and usually lower than, that of the incident photons. In a gas, Raman scattering can occur with a change in energy of a molecule due to a transition (see energy level). Chemists are primarily concerned with the transitional Raman effect.
