'''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)ficient#Optics|transmission]] of various frequencies of light is essential for applications ranging from window glass to [[optical fiber cable|fiber optic transmission cables]] and [[infrared]] (IR) [[heat-seeking missile]] detection systems.

It has therefore become quite clear that light scattering is an extremely useful tool for monitoring the dynamics of structural relaxation in glasses on various temporal and spatial scales and therefore provides an ideal tool for quantifying the capacity of various glass compositions for guided light wave transmission well into the far infrared portions of the electromagnetic spectrum.<ref>{{cite book|author=Measures, R.M.|title=Structural Monitoring with Fiber Optic Technology|url=http

*[[Mie theory|Mie scattering]] is a broad class of scattering of light by spherical particles of any diameter. The scattering intensity is generally not strongly dependent on the wavelength, but is sensitive to the particle size. Mie scattering coincides with Rayleigh scattering in the special case where the diameter of the particles is much smaller than the wavelength of the light(contracted; show full)
