Rayleigh scattering is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. In summary, this is a process in which interacts radiation and matter. This phenomenon is a result of the electric polarizability of the particles such as electrons. Every light wave has its electric field. When the electric field acts on the charges of a particle, it moves at the same frequency. Consequently, the particle becomes a small radiating dipole. The resulting radiation is what we perceive as light.
