Scattering is the phenomenon by which a beam of light is redirected in many different directions when it interacts with a particle of matter.

Scattering of light depends on the

i. Size of the particle which scatters the light.

When the scattering cross-section of the particles is small, less light is scattered.

ii. Wavelength of light.
Light with a higher wavelength is scattered less than light with a lesser wavelength.
