Dispersion relation in air Air is one of the polyatomic gases more deeply studied, and currently it is known that there are basically two different mechanisms that cause absorption of acoustic waves: the viscothermal losses (or classical absorption) and the oxygen and nitrogen molecular relaxation processes. 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.

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. In the physical sciences and electrical engineering, dispersion relations describe the effect of dispersion on the properties of waves in a medium. A dispersion relation relates the wavelength or wavenumber of a wave to its frequency. so the dispersion relation is useful for determining the group velocity of the wave packet inside a medium , i am sorry i have another question , considering an electron moving inside a solid , after solving the Schrodinger equation ,say the following E,k diagram is obtained This lecture derives and discussed the dispersion relation in electromagnetics.

Dispersion relation Book - iMusic

More exactly, the dispersion relation is a relation connecting the real part of the scattering amplitude (in the more general case, the Green function) with certain types of integrals of its imaginary part. The relationship between frequency (usually expressed as an angular frequency, ω) and wave number is known as a dispersion relation. Just as the concept of photons is used to express the particle-like aspects of electromagnetic waves, the term phonon is used to refer to lattice vibrations where they behave in a particle-like manner.
