Question

Stokes and antistokes lines observed in Raman scattering is due to _________ of light.(A) reflection
(B) elastic scattering(C) inelastic scattering
(D) dispersion

Answer 1

Stokes and Antistokes lines observed in Raman scattering are due to the (C) inelastic scattering of light.

Raman scattering is a phenomenon discovered by Indian physicist CV Raman. It involves the scattering of light when there is a transfer of vibrational energy from an excited higher state, to a lower energy state. It utilises the principle of inelastic collisions between particles- in this case, photons and particulate matter. Stokes and Antistokes lines are associated phenomena of Raman scattering.
