Please answer problem 1A part A and B

/ 26 Total / 100 PROBLEM 1A: A piece of glass (n = 1.5) is submerged in water (n = 1.33). (A) (6pts) A beam of light (shown in the diagram) travels such that it just barely achieves total internal reflection before exiting the right side. Calculate the angle 0. (B) (3pts) Consider the same piece of glass, but surrounded by air. If another beam of light were initially traveling along the same trajectory, would it also achieve total internal reflection?
