The angle of incidence of a light beam in air onto a reflecting surface is continuously variable. The reflected ray is found to be completely polarized when the angle of incidence is 47.5 degrees.
What is the index of refraction of the reflecting material?
If some of the incident light (at an angle of 47.5 degrees) passes into the material below the surface, what is the angle of refraction?
