abstract:The Fresnel equations (or Fresnel conditions), deduced by Augustin-Jean Fresnel , describe the behaviour of light when moving between media of differing refractive indices. The reflection of light that the equations predict is known as Fresnel reflection.
The Fresnelwaverayequationis deducedby use of the fundamentalequations of crystaloptics. The crystal optics questionis solvedbyFresnel wave ray equation cooperating withMaxwellequation.
