We know that the index of refraction of materials can help identify those materials. When a light beam is shined onto a surface with an angle of incidence of 65.3°, the reflected ray is found to be completely polarized. (a) What is the index of refraction of the reflecting material?

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

this is an example of "committed" time.
