Raman effect or Raman scattering is popularly known as an inelastic scattering of a photon. When light is scattered from an atom or molecule, most photons are elastically scattered with almost the same energy (frequency) and wavelength as the incident photons. But a small fraction of the photons is scattered by excitation. The frequency of scattered photons is lower than the frequency of the incident photons.

For his discovery, Raman was the first Indian scientist to be honoured with the prestigious awarded the Nobel Prize in Physics in 1930.

Every year a different theme is selected and all the forth programmes and activities are based around that theme. Various activities are organised on the day, like debates, quiz competitions, exhibitions, lectures, in which college students, school students and teachers too participate.
