We know that the index of refraction of materials can help identify those materials. A light beam is shined onto a surface a reflected ray and is found to be completely polarized when the angle of incidence is 56.5°,
(a) What is the index of refraction of the reflecting material?
(b) What is the angle of refraction if some light passes through the surface of the material?
We know that the index of refraction of materials can help identify those materials.
