Question

A ray of light is incident on a plane mirror. Find the angle rotated by the reflected ray if:

The mirror is rotated by 2(theta) clockwise and incident ray is also rotated by (theta) anti clockwise.

Answer 1

Answer:

The incident ray is rotated by (theta) anti-clockwise

The mirror is rotated by 2(theta) clockwise

So the reflected ray is rotated by (2×2(theta) + (theta))= 5(theta) clockwise

Explanation:

Answer 2

Answer:

angle rotated by reflected ray = 5θ
