Question

Two plane mirrors are inclined to each other at an angle ${60}^{\circ }.$ If a ray of light incident on the first mirror is parallel to the second mirror, it is reflected from the second mirror

• A. Perpendicular to the first mirror
• B. Parallel to the first mirror
• C. Parallel to the second mirror
• D. Perpendicular to the second mirror

Answer 1

The correct option is B Parallel to the first mirror

Let the two mirror be M₁ and M₂ as shown in the figure.

From the figure we can see that the reflected ray from the second mirror is parallel to the first mirror.

Hence the correct answer is option (B).
