Nist reflectivity

WebbOverview. When light strikes the interface between a medium with refractive index n 1 and a second medium with refractive index n 2, both reflection and refraction of the light may occur. The Fresnel equations give the ratio of the reflected wave's electric field to the incident wave's electric field, and the ratio of the transmitted wave's electric field to the … Webb1 mars 1998 · Part II develops the necessary theory of reflection, beginning with basic definitions and equations and ending with the relevant measurement …
