Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be accounted for in geometric optics.

## Ray (optics)

1 linksIdealized geometrical model of light, obtained by choosing a curve that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow.

Ray optics or geometrical optics does not describe phenomena such as diffraction, which require wave optics theory.

## Coherence theory (optics)

0 linksIn physics, coherence theory is the study of optical effects arising from partially coherent light and radio sources.
