| dispersion relation | <radiobiology> For a given wave, the dispersion relation relates the temporal frequency of a wave (w, or omega) to its wavenumber k and other physical quantities characteristic of the system. Dispersion relations can be quite simple (for example, w = k c for light, c being the speed of light), and they can also be quite complex, with interesting mathematical structure. The dispersion relation and its mathematical structure provide important information about the wave, including the phase and group velocities. Note that the meaning of dispersion relation is different in plasma physics than in other fields. (09 Oct 1997) |
