Dispersion Dis*per"sion, n. [CF. F. dispersion.] 1. The act or process of scattering or dispersing, or the state of being scattered or separated; as, the Jews in their dispersion retained their rites and ceremonies; a great dispersion of the human family took place at the building of Babel. [1913 Webster]

The days of your slaughter and of your dispersions are accomplished. --Jer. xxv. 34. [1913 Webster]

2. (Opt.) The separation of light into its different colored rays, arising from their different refrangibilities. [1913 Webster]

{Dispersion of the optic axes} (Crystallog.), the separation of the optic axes in biaxial crystals, due to the fact that the axial angle has different values for the different colors of the spectrum. [1913 Webster]
