Chapter 25, Problem 2PE
Show that when light reflects from two mirrors that meet each other at a right angle, the outgoing ray is parallel to the incoming ray, as illustrated in the following figure.
Figure 25.51 A corner reflector sends the reflected reflected ray back in a direction parallel to the incident ray, independent of incoming direction.

An incoming ray of light strikes the mirror at an angle of 30˚ relative tothe normal. What is the angle between the incident ray and the reflectedray?
A. 15 ˚

Light travels from air into water (n=1.33). The angle of incidence is 40.5 degrees. The refracted ray has what angle with respect to the line normal to the surface? That is, what is the angle of refraction?
Give your answer in degrees.
The diagram illustrates a light ray originating from the floor of a small room, making an angle ϕ= 37° with the floor. The ray reflects from a vertical mirror that is a horizontal distance d= 1.1 m from the source, as shown. If the horizontal distance between opposing vertical walls is w= 4.7 m, how high h on the wall opposing the mirror does the ray strike?
