7. Two mirrors A and B are placed at right angles to each other as shown in
Fig. given below. A ray of light incident on mirror A at an angle of
25degree falls on mirror B after reflection. The angle of reflection for the
ray reflected from mirror B would be चित्र दर्पण A यदि पर आपतित कोण 25 डिग्री
का बना है तो दर्पण B पर परावर्तित कोण कितने डिग्री का बनेगा
