Raman Effect
          The Raman Effect or Raman Scattering is the change in the wavelength of light that occurs when a beam of light is deflected by molecules.
          The scattering is due to change in wavelength of light when it enters a medium. When a light beam travels through a  transparent medium, a small fraction of light emerges out in directions other than that of the incoming beam.
