Dispersion - definition of dispersion by The Free Dictionary
n. 1. Also, dispersal. an act or instance of dispersing or a state of being dispersed. 2. a. the variation of the index of refraction of a transparent substance, as glass, with the wavelength of light. b. the separation of white or compound light into its respective colors, as in the formation of a spectrum by a prism.

Dispersion relation - Wikipedia
A dispersion relation relates the wavelength or wavenumber of a wave to its frequency. Given the dispersion relation, one can calculate the frequency-dependent phase velocity and group velocity of each sinusoidal component of a wave in the medium, as a function of frequency. In addition to the geometry-dependent and material-dependent ...

Understanding dispersion relation - Physics Stack Exchange
A dispersion relation tells you how the frequency ω ω of a wave depends on its wavelength λ λ --however, it's mathematically better to use the inverse wavelength, or wavenumber k = 2π/λ k = 2 π / λ when writing equations because the phase velocity is. vphase = ω/k v p h a s e = ω / k. and the group velocity is.

Dispersion and Scattering of Light | Brilliant Math & Science Wiki
Dispersion of light occurs when white light is separated into its different constituent colors because of refraction and Snell's law. White light only appears white because it is composed of every color on the visible spectrum. Although they are very close, the index of refraction for each color is unique in non-vacuous materials. These unique indices cause each wavelength to follow a ...

Statistical dispersion
Measures of statistical dispersion A measure of statistical dispersion is a nonnegative real number that is zero if all the data are the same and increases This means that if a random variable has a dispersion of then a linear transformation for real and should have dispersion , where is the absolute wikipedia.org

Why second moment about mean is better at describing spread than the first one? Dispersion is usually used as a measure of inaccuracy of a measurement. It's defined as second moment about mean. Why not define dispersi...
Because, a lot of the time, the utility function is concave, therefore we need a convex function to penalize dispersion/error. in $l^3$ space study Least Cubic problems instead of Least Square problems, and there is someone posting a question online - "Why do we always measure dispersion
