What is scattering of light? On what factors does it depend ?

Explanation

The deflection of light by minute particles and molecules/atoms in all directions is known as scattering of light.
The amount of scattering (i.e., extent of deflection) of light depends on the frequency (colour) of light and the size of the particles responsible for scattering.
(1) Very fine particles scatter mainly blue light. Bigger particles scatter light of longer wavelength.
(2) If the scattering particles are very large, the scattered light appears white as light of all wavelengths in the visible region is scattered.
