{wiki=Rayleigh–Gans_approximation}
The Rayleigh–Gans approximation is a theoretical framework used in scattering theory, particularly to analyze how electromagnetic waves scatter off small particles. It is an extension of the Rayleigh scattering theory, which applies primarily to particles whose size is much smaller than the wavelength of the incident light.
