Rayleigh scattering

The @S05487@ of light by particles and molecules which are much smaller than the @W06659@ of the light. In the ideal case, the process is one of pure dipole and induced dipole interactions with the electric field of the light wave. The @S05487@ cross section for light of @W06659@ \(\lambda \) is proportional to \(\lambda ^{-4}\).
