Solution

Dear Student

If a mirror is rotated by $θ$ then the reflected ray is rotated by 2 $θ$ similarly if the reflected ray is rotated by 4A then the mirror must have been rotated by 2A in clockwise direction.

The angle between the incident and reflected rays is $90^{o}$ . If the plane mirror is rotated by $10^{o}$ about O in the anti-clockwise direction in the plane perpendicular to the mirror, then the angle between the incident and reflected rays will be _______ $^{0}$ .

In the given figure if the mirror is rotated by an angle $θ$ in the clockwise direction. Then the angle of incident becomes equal to:
