Scattering in physics

About scattering in physics

Rayleigh scattering refers to the scattering of visible light or other electromagnetic radiation by particles smaller than the wavelength of the radiation. Rayleigh scattering is wavelength-dependent.

Mie scattering refers to the scattering of visible light or other electromagnetic radiation by spherical particles with diameters approximately equal to the wavelength of incident light present in the lower atmosphere. Mie scattering causes all wavelengths of light to be reflected back into the atmosphere in equal proportions and is thus responsible for the white appearance of clouds.

Non-selective scattering is similar to Mie scattering and takes place when the particles are much larger than incident light. This type of scattering is not wavelength dependent and is the primary cause of atmospheric haze.
