The Dispersion of Elements
In addition to making , scatter them. The elements that are made both inside the as well as the ones created in the intense heat of the supernova explosion are spread out in to the interstellar medium.
Velocity Dispersion
Rotationally supported objects (left) have the majority of stars orbiting in the same direction. With velocity dispersion (right), approximately equal numbers of stars orbiting in all directions.
Dispersion - The separation of white light according to wavelength. Dispersion produces a rainbow-like spectrum

Dispersion
(a) During refraction, rays can be deviated (changed in direction) by angles related to the refractive index of the medium. However, the refractive constant of any medium varies with the wavelength of the transmitted radiation.
LIGHT DISPERSION
Breaking light into its various wavelengths is light dispersion. Transparent substances disperse light because red light (longer wavelengths) is refracted less than blue light (shorter wavelengths).

dispersion - Separation, from white light, of different wavelengths being refracted by different amounts.
doppler shift - Apparent change in wavelength of the radiation from source due to its relative motion in the line of sight.

Dispersion
Visible light is actually made up of different colors. Each color bends by a different amount when refracted by glass. That's why visible light is split, or dispersed, into different colors when it passes through a lens or prism.

Velocity dispersions suggest that about 90% of the mass in clusters is not in individual galaxies.
velocity dispersion - (n.)
A measure of the average velocity of stars in a group or cluster with random internal motions. In globular clusters and elliptical galaxies, the velocity dispersion can be used to infer the central mass.
Prismatic dispersion by our atmosphere is most evident when a star or planet is seen near the horizon. It results from refraction being less for the longer wavelengths where the red appears nearer the horizon and violet toward the zenith.
VELOCITY DISPERSION - Random motions (orbits) of stars which support a self-gravitating body against collapse. Motions can be either ordered or random.
Velocity Dispersion Method
A method of finding a galaxy's mass by observing the range of velocities within the galaxy.

Interstellar Dispersion
The velocity of propagation of electromagnetic waves depends upon frequency. Thus, unless the wave is highly monochromatic, the energy in the wave arrives at the receiver at differing times.

The amount of diffractive bending experienced by a ray is a function of wavelength; thus dispersion occurs, although dispersion is in the opposite sense to that produced by refraction.
The possible applications of anomalous dispersion are varied and interesting, and have recently had much attention given to them. W. H. Julius holds that this sole fact robs of objective reality almost all the features of the sun, An al ou.
However, modern designs using apochromatic optics built with special, extra low-dispersion materials essentially eliminate these problems.
The dispersion relation is linear and the constant of proportionality is Planck's constant h, yielding the useful relations for kinematic studies, E = h ν ...
Sandra Faber and Robert Jackson discovered in 1976 a simple relation between the spread of velocities (called the velocity dispersion) and the luminosity of elliptical galaxies.
The resulting high-dispersion spectra are then imaged electronically. In the latter, the classic single spectrograph slit is replaced with a slit mask -- a metal plate containing many small, precut slits, ...

Military advantage High levels of population dispersion and, to a lesser extent, the presence of mountainous terrain increased the chance of conflict.
It has at least one element of flint glass and another of crown glass - the dispersion of the latter compensating for the chromatic aberration of the former.
