'''Light scattering''' is a form of [[scattering]] in which [[light]] in the form of propagating energy is scattered. Light scattering can be thought of as the deflection of a [[ray (optics)|ray]] from a straight path, for example by irregularities in the propagation [[optical medium|medium]], [[light scattering by particles|particles]], or in the interface between two media. Deviations from the [[law of reflection]] due to irregularities on a surface are also usually considere(contracted; show full)e substances, which includes their [[symmetry group]] and [[Bravais lattice]]. For example, the seven different [[crystalline]] forms of [[quartz]] silica ([[silicon dioxide]], SiO<sub>2</sub>) are all clear, [[transparent materials]].<ref>{{cite journal|doi=10.1103/RevModPhys.40.167|title=Brillouin Light Scattering from Crystals in the Hydrodynamic Region|year=1968|last1=Griffin|first1=Allan|journal=Reviews of Modern Physics|volume=40|pages=167|bibcode=1968RvMP...40..167G}}</ref>

*[[Rayleigh scattering]] is the [[Elasticity (physics)|elastic]] scattering of light by molecules and [[Atmospheric particulate matter|particulate matter]] much smaller than the wavelength of the incident light. It occurs when light penetrates gaseous, liquid, or solid phases of matter.  Rayleigh scattering intensity has a very strong dependence on the size of the particles (it is proportional to the third power of their diameter). It is inversely proportional to the fourth power of the wavelength of light(contracted; show full)
