Dispersion — may refer to: In physics: The dependence of wave velocity on frequency or wavelength: Dispersion (optics), for light waves Dispersion (water waves) Acoustic dispersion, for sound waves Dispersion relation, the mathematical description of… … Wikipedia
Modal dispersion — is a distortion mechanism occurring in multimode fibers and other waveguides, in which the signal is spread in time because the propagation velocity of the optical signal is not the same for all modes. Other names for this phenomenon include… … Wikipedia
Taylor dispersion — is an effect in fluid mechanics in which a shear flow can increase the effective diffusivity of a species. Essentially, the shear acts to smear out the concentration distribution in the direction of the flow, enhancing the rate at which it… … Wikipedia
Compilation of atmospheric dispersion models — Atmospheric dispersion models are computer programs that use mathematical algorithms to simulate how pollutants in the ambient atmosphere disperse and, in some cases, how they react in the atmosphere. The dispersion models are used to estimate or … Wikipedia
Dynamical friction — is a term in astrophysics related to loss of momentum and kinetic energy of moving bodies through a gravitational interaction with surrounding matter in space. It is sometimes referred to as gravitational drag, and was first discussed in detail… … Wikipedia
M-sigma relation — The M sigma (or MBH σ) relation is an empirical correlation between the stellar velocity dispersion σ of a galaxy bulge and the mass M of the supermassive black hole at the galaxy s center. The relation can be expressed mathematically as A recent … Wikipedia
Stellar kinematics — is the study of the movement of stars without needing to understand how they acquired their motion. This differs from stellar dynamics, which takes into account gravitational effects. The motion of a star relative to the Sun can provide useful… … Wikipedia
