Refraction. Computer artwork of parallel light beams passing through a glass sphere and converging to the right of the sphere. The converging rays do not form a perfect focus at right due to spherical aberration. Refraction is the change of direction of a wave when it passes from one medium to another. The change in medium causes a change in speed and wavelength.
