Wavelength scattering

Dust Micron-sized particles of silicate in the interstellar medium responsible for short-wavelength scatter - dust particles become covered with water-ice mantels. 

In Rayleigh scatter, the wavelength of the absorbed and emitted photons are the same. Ultraviolet wavelengths scatter more than visible. Rayleigh scatter can be a significant problem when the wavelength pair overlaps (less than 50 nm) and instruments do not have filter accommodations and adjustable slits. 

Consider a monochromatic beam of electromagnetic waves with a given wave number vector ko (ko is a vector in the direction of propagation of the plane wave with absolute magnitude ko = 27t/A, where X is the wavelength), scattered from a system of N molecules. The scattered wave number vector is denoted by k. Two important assumptions are made regarding this process. (1) The incident and the scattered beam have the same wavelength, i.e.,...

In addition to coherent contributions, there are incoherent contributions to light scattering In which fractons of characteristic size smaller than the optical wavelength scatter Independently from each other. In that case, the scattered intensity is the sum of the individual scattering intensities, while for...
