Incorporates the theory of [[quantum mechanics]] into optics. Light is described as a beam of particles called [[photons]]. Because of the wave matter duality of quantum theory, this photons have wave like properties.  In this scheme, the frequency of the photons determines the color of the light, and the intensity of the light is determined by the number of photons. Modern optics has a large number of practical applications, like the [[laser]] and optic fibers.
