Two plane mirrors are perpendicular to each other. A ray after suffering reflection from the two mirrors will be

Options

  1. Aperpendicular to the original ray
  2. Bparallel to the original ray
  3. Cparallel to the first mirror
  4. Dat 45^ to the original ray

Correct answer

B. parallel to the original ray

Step-by-step solution

Here, angular deviation aligned &=2 -2 &=2 -2 2 = aligned Hence, final emergent ray is parallel to incident ray.
