Chapter 18, Problem 15P
A light ray travels inside a horizontal plate of glass, striking its upper surface at an angle of incidence of 60°. This ray is totally internally reflected at the glass-air boundary. A liquid is then poured on top of the glass. What is the largest index of refraction that the liquid could have such that the ray is still totally internally reflected?

A ray of monochromatic light is traveling through air and is incident upon a block of transparent material with an index of refraction of 2.01. If the angle of incidence is 70.2 degrees with respect to the normal of the interface boundary, what is the angle of refraction in the transparent material?
From inside an aquarium, a ray of light is directed at the glass so that the angle of incidence in the water is 52 degrees. At what angle will the rays emerge from the glass?
A light ray travels from air (n=1.00) into a crown glass (n=1.52) with an angle of incidence of 49 degrees. The light ray continues to travel through the crown glass material into the diamond (n=2.42). At what angle does the light ray make with the normal line as it enters the diamond?
