A light ray traveling in a slab of crown glass surrounded by air. The ray is incident on the right surface at an angle of 55° with the normal and then reflects from points A, B, and C.

(a) At which of these points does part of the ray enter the air?

(b) If the glass slab is surrounded by carbon disulfide, at which point does part of the ray enter the carbon disulfide? (Select all that apply. The index of refraction of carbon disulfide is 1.628, and the index of refraction of the glass is 1.52.)
