Rayleigh scattering results from the electric polarizability of the particles. The oscillating electric field of a light wave acts on the charges within a particle, causing them to move at the same frequency. The particle, therefore, becomes a small radiating dipole whose radiation we see as scattered light.

What is Rayleigh law of scattering?

(Also called Rayleigh scattering.) ... According to this law, first derived in 1871 by Lord Rayleigh using simple dimensional arguments, scattering in all directions by an object is inversely proportional to the fourth power of the wavelength of the illumination.

What is Rayleigh scattering used for?

Rayleigh scattering is mostly used for temperature measurements. 2-D measurements can be performed. Examples measurements can be performed. Examples will be shown.
