Define the plane of incidence. What does it mean when the reflectance is equal to zero, and equal to one.

Solution

In describing reflection and refraction inoptics, the plane of incidence (also called themeridional plane[citation needed]) is the planewhich contains the surface normal and thepropagation vector of the incoming radiation. In wave optics, the latter is the k-vector, or wavevector, of the incoming wave. When reflection is specular, as it is for a mirror or other shiny surface, the reflected light also lies in the plane of incidence. The orientation of the incident light\'s polarization with respect to the plane of incidence has an important effect on the strength of the reflection.,,

The reflection and refraction of plane waves at a boundary between two media of differing properties are well known, following Snell\'s law and the Fresnel formulas. A plane wave incident on a dielectric discontinuity is split into two waves; the transmitted wave proceeding into the second medium and the reflected wave propagating back into the incident medium from which the following relation is derived.

n1 sin i = n1 sin r = n2 sin t (2-30)

where i, r, and t are the incident , reflected and transmitted angles, and n1 & n2 are the refractive indices of the incident and transmitted mediums. As (r = i) then the transmitted angle t into the second medium is defined as :
