Two plane mirrors are hinged along one edge and set at right angles to one another as shown in Figure 9.83. A light ray enters the system, striking mirror 1 with an angle of incidence of 45?. Draw a diagram showing the direction in which the ray will exit the system. This device is called a corner reflector and is the basis for the design of bicycle reflectors and some highway signs.
