Dispersion may refer to:
In physics:
- The dependency of wave velocity on frequency.
- Dispersion relation describes the interrelation of wave properties like wavelength, frequency, velocities, refraction index, attenuation coefficient.
- Dielectric dispersion
- Dispersion (optics) is the phenomenon in which the phase velocity of a wave depends on its frequency, or alternatively when the group velocity depends on the frequency.
- Dispersion (water waves). In fluid dynamics, dispersion of water waves generally refers to frequency dispersion, which means that waves of different wavelengths travel at different phase speeds.
- Acoustic dispersion is the phenomenon of a sound wave separating in into its component frequencies as it passes through a material.
- Dispersive mass transfer, in fluid dynamics, the spreading of mass from areas of high to low concentration
- London dispersion force, an instantaneous induced dipole-induced dipole, is one of the Van der Waals forces
- Modal dispersion, spreading signals in multimode fibers and waveguides by a distortion mechanism
In other sciences:
- Dispersion (chemistry), a system in which particles are dispersed in a continuous phase of a different composition
- Dispersion (geology), a process whereby sodic soil disperses when exposed to water
- Dispersion (materials science), the fraction of atoms of a material exposed to the surface
- Biological dispersal, the distribution of spores, fruits and their seeds, etc.
In other uses:
- Dispersion (finance), a measure for the statistical distribution of portfolio returns
- Statistical dispersion, quantifiable variation of measurements of differing members of a population
- Coefficient of dispersion, a measure to quantify whether a set of observed occurrences are relatively clustered or dispersed
- Price dispersion, variation in prices across sellers of the same item
- Wage dispersion refers to the amount of variation in wages encountered in an economy
