A change in the phase of a wave, often resulting from reflection or transmission at an interface, which affects how waves combine with one another.

Optical path difference (OPD) refers to the difference in the distance that light travels in two different paths, taking into account the refractive index of the medium through which it travels. This concept is crucial in understanding phenomena like interference patterns, where the interaction of light waves can lead to constructive or destructive interference based on their phase differences, which are influenced by the optical path difference. OPD is particularly significant in situations involving thin films, where light reflects off different surfaces and creates patterns based on the varying distances traveled by the light waves.
