'''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)

==Static and dynamic scattering==
A common dichotomy in light scattering terminology is [[static light scattering]] versus [[dynamic light scattering]]. In static light scattering, the experimental variable is the time-average intensity of scattered light, whereas in dynamic light scattering it is the fluctuations in light intensity that are studied.  Both techniques are typically encountered in the field of colloid and polymer characterization. They also have a broad range of other applications.
  Scattering is what also causes you to be able to see yourself in the mirror.  

==Critical phenomena==
Density fluctuations are responsible for the phenomenon of [[critical opalescence]], which arises in the region of a continuous, or second-order, phase transition. The phenomenon is most commonly demonstrated in binary fluid mixtures, such as [[methanol]] and [[cyclohexane]]. As the critical point is approached the sizes of the gas and liquid region begin to fluctuate over increasingly large length scales. As the length scale of the density fluctuations approaches the wavelength of (contracted; show full)
