A dispersion relation relates the wavelength or wavenumber of a wave to its frequency. Given the dispersion relation, one can calculate the phase velocity and group velocity of waves in the medium, as a function of frequency. The transport properties of solids are closely related to the energy dispersion relations E(~k) in these materials and in particular to the behavior of E(~k) near the Fermi level. Con- versely, the analysis of transport measurements provides a great deal of information on E(~k).

A dispersion relation relates the wavelength or wavenumber of a wave to its frequency. In a prism, dispersion causes different colors to refract at different angles, splitting white light into a rainbow of colors.

4. As we shall see in the following chapters, this relation is an important source of information on the stability and accuracy properties of … In a dispersive medium, the phase speed itself depends upon the frequency of the wave, making the relationship between wavelength and frequency nonlinear. , is known as the dispersion relation. For periodic waves in nondispersive media (that is, media in which the wave speed is independent of frequency), frequency has an inverse relationship to the wavelength, λ (lambda). This paradigm leads to a dispersion relation linking the wave frequency and the complex wave number, where the imaginary component of the wave number defines the attenuation rate. Recent field measurements (e.g., Cheng et al., 2017 ; Meylan et al., 2014 ), which are far more comprehensive than earlier experiments in terms of duration and extent, are predominantly in the long‐wavelength regime. In physical sciences or electrical engineering, dispersion relations explain the effect of dispersion in a intermediate on the properties of a wave traveling with in that medium.
