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

Scattering is the natural phenomenon where the light rays are directed in different directions when it interacts with small particles.

Scattering depends on the size of the particles, if the particles are very small then it will scatter light of smaller wavelength (blue light) and if the particle size is slightly bigger then it will scatter light of greater wavelength (red light). If the particles are much bigger in size then they will scatter white light.
