Question

In the given figure if the mirror is rotated by an angle $\theta$ in the clockwise direction, then the angle of incidence becomes equal to:

• A. X + θ
• B. θ
• C. X - θ
• D. X

Answer 1

The correct option is A

X + θ

If the mirror is rotated by angle $\theta$, the angle of incidence is also increased by angle $\theta$.
