refraction


refraction: Retardation, and--in the general case-- redirection, of a wavefront passing through (a) a boundary between two dissimilar media or (b) a medium having a refractive index that is a continuous function of position, e.g., a graded-index optical fiber. Note: For two media of different refractive indices, the angle of refraction is closely approximated by Snell's Law.
