1. dispersion

   Dispersion generally refers to the spreading out or distribution of something over an area or volume. In statistics, it describes the degree to which values in a data set vary from the mean. While in physics, it's the phenomenon by which the phase velocity of a wave depends on its frequency. The meaning of dispersion varies depending on the context in which it is used.

1. Dispersion

   In optics, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency, or alternatively when the group velocity depends on the frequency. Media having such a property are termed dispersive media. Dispersion is sometimes called chromatic dispersion to emphasize its wavelength-dependent nature, or group-velocity dispersion to emphasize the role of the group velocity. Dispersion is most often described for light waves, but it may occur for any kind of wave that interacts with a medium or passes through an inhomogeneous geometry, such as sound waves. A material's dispersion is measured by its Abbe number, V, with low Abbe numbers corresponding to strong dispersion.

In antiaircraft gunnery, the scattering of shots in range and deflection about the mean point of explosion. 3. The spreading or separating of troops, materiel, establishments, or activities which are usually concentrated in limited areas to reduce vulnerability. 4. In chemical and biological operations, the dissemination of agents in liquid or aerosol form. 5. In airdrop operations, the scatter of personnel and/or cargo on the drop zone. 6. In naval control of shipping, the reberthing of a ship in the periphery of the port area or in the vicinity of the port for its own protection in order to minimize the risk of damage from attack. See also circular error probable; convoy dispersal point; delivery error; deviation; dispersion error; horizontal error.
