Two mirrors A and B are placed at right angles to each other as shown in Fig.16.4.
A ray of light incident on mirror A at an angle of 250 falls on mirror B after reflection. The angle of reflection for the ray reflected from mirror B would be
The ray will be reflected from mirror A at 25o and would strike the mirror B at 65o and hence according to the laws of reflection would be reflected from mirror B at 65o as shown in the figure below: -
