dis·per·sion
(dĭ-spûr′zhən) The separation of light or other radiation into individual components, usually according to frequency and wavelength. When a beam of white light (light that contains all colors) passes through a prism, for example, dispersion causes it to separate into the seven colors of the rainbow.
