A beam of light traveling in air encounters a rectangular piece of plastic covering a rectangular piece of glass.
If the angle of incidence is 45 degrees at the air-plastic interface, what is the angle of refraction for the beam in the glass? (When you get the answer, compare it to the answer for the previous problem.)
Previous problem : F - Refraction with two media.
