Options

  1. ARayleigh scattering.
  2. BRaman effect.
  3. CPhotoelectric effect.
  4. DRutherford scattering.

Correct answer

B. Raman effect.

Step-by-step solution

Ramen effect is the process of scattering of light particles by molecules of medium. The scattering occurs due to a change in the wavelength of light as it enters the medium. When light is scattered by molecule and the frequency of the scattered light is changed, this phenomenon is explained by Raman effect. When light wave strike a medium, some of the energy of incident light may be increased or decreased the molecules of the medium, hence the scattered light may have frequency or wavelength increased or decreased
