Dispersion (optics) - Wikipedia
Dispersion causes a rainbow's spatial separation of a white light into components of different wavelengths (different colors). However, dispersion also has an effect in many other circumstances: for example, group-velocity dispersion causes pulses to spread in optical fibers, degrading signals over long distances; also, a cancellation between group-velocity dispersion and nonlinear effects ...

The dependence of wave velocity on frequency or wavelength: Dispersion (optics), for light waves Dispersion (water waves), for water waves Acoustic dispersion, for sound waves Dispersion relation, the mathematical description of dispersion in a system Modal dispersion, spreading of signals in multimode fibers and waveguides by a distortion mechanism Polarization mode dispersion, a form of ...
Dispersion | Meaning, Examples, & Optics | Britannica
dispersion, in wave motion, any phenomenon associated with the propagation of individual waves at velocities that depend on their wavelengths. Waves of any type can be described by a dispersion relation in which the wave frequency ω is given in terms of the wavenumber k, where k = 2π/λ, where λ is the wavelength. The velocity of a wave is ω/ k, and waves in which the velocity ω/ k is ...

1.6: Dispersion - Physics LibreTexts
Dispersion is defined as the spreading of white light into its full spectrum of wavelengths. More technically, dispersion occurs whenever the propagation of light depends on wavelength. Figure $1.6.2$: Even though rainbows are associated with six colors, the rainbow is a continuous distribution of colors according to wavelengths.
Measures of Dispersion - GeeksforGeeks
Dispersion refers to the degree to which data values in a dataset are spread out or scattered around an average (such as the mean or median). It helps us understand the variability or consistency within the data — whether the values are closely grouped or widely spread. In statistics, measures of dispersion are numerical values that describe the extent of variation among data points. They ...

Dispersion - Simple English Wikipedia, the free encyclopedia
Dispersion A diagram of light dispersion through a prism In wave physics, Dispersion is the idea that the frequency of a wave influences its velocity (speed). Dispersion is most easily seen in the refraction of light, when all the colors inside white light become separated by a prism.
