Scattering of Light

Molecules of a medium after absorbing incoming light radiations emit them in all directions. This phenomenon is called scattering.
According to scientist Rayleigh, intensity of scattered light ∝ 1/λ4. Some phenomena based on scattering are as follows:
  • Sky looks blue due to scattering.
  • At the time of sunrise or sunset sun looks reddish.
  • Danger signals are made of red color.
Elastic scattering When the wavelength of radiation remains unchanged, the scattering is called elastic.
Inelastic scattering (Raman’s effect) Under specific condition, light can also suffer inelastic scattering from molecules in which its wavelength changes.
