The angle of incidence of a light beam in air onto a reflectingsurface is contin

Question

The angle of incidence of a light beam in air onto a reflectingsurface is continuously variable. The reflected ray is found to becompletely polarized when the angle of incidence is 56.0°. (a) What is the index of refraction of thereflecting material?
1
(b) If some of the incident light (at an angle of 56.0°) passes into the material below thesurface, what is the angle of refraction?
2°

2°

Explanation / Answer

a) n = tan(56.0) = 1.48 b) 90.0 - 56.0 = 34.0o
