Ray (optics)

In optics, a ray is an idealized geometrical model of light or other electromagnetic radiation, obtained by choosing a curve that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow.: 2 Rays are used to model the propagation of light through an optical system, by dividing the real light field up into…
