Question

16 Light strikes a mirror as shown in Figure 32.18. This mirror has another mirror placed at right angles to it. Such an arrangement of mirrors is known as a corner reflector. At what angle does the light get reflected back (i.e. what angle is the outgoing light at when it crosses the dotted line)? Mirror Surfaces 45° 45° Incoming light 20° Figure 32.18 Two mirrors are placed a right angles to one and other. This arrangement of mirrors reflects light in a particular fashion, making them useful for a range of purposes.
