In ray-tracing we obtain approximate solutions to Maxwell's equations that are valid as long as the light waves propagate through and around objects whose dimensions are much greater ...
WebRay optics, also known as geometrical optics, is the study of simple properties of light and optical instruments by assuming that light travels in a straight line. Ray optics deals with the geometry of the light. Light always travels in a straight line and the direction in which the light rays propagate is called the ray of light.
