| Description | The analysis of the phenomenon of refraction of electromagnetic waves at the interface between two media suggests that their velocity when passing from one medium to another changes. It has previously been shown that the phase velocity of a wave in a medium is determined by the expression $v_{ph}$ = c/n, where n is the medium refractive index. Numerous measurements indicate a dependence of the propagation velocity and the refractive index on the frequency (or wavelength). The wave velocity (or the refractive index) dependence on frequency is called dispersion . This phenomenon is present in all media except vacuum, and we considered several specific cases of dispersion in Chapters 6, 7, and 11. The phenomenon of light dispersion can also be observed when a beam of white light passes through a glass prism. One can observe a pattern of multicolor bands on a screen placed behind the prism. This pattern is a result of the decomposition of white light into its spectral components that have different colors and hence different wavelengths.
