Reflectivity law

Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves. The law of reflection says that for specular reflection (for example at a mirror) the angle at which the wave is incident on the surface equals the angle … WebDefinitions: “S” and “P” polarizations 2. “P” polarization is the parallel polarization, and it lies parallel to the plane of incidence. 1. “S” polarization is the perpendicular polarization, and
