Question

If a light ray is made to strike a plane surface, as shown in the picture below, the reflected ray will head _____.

  1. Towards the torch
  2. Towards the back of the surface
  3. Above the torch
  4. Below the torch

hintHint:

Law of reflection.

The correct answer is: Towards the torch


    By law of reflection incident angle is equal to reflected angle, incident angle in the given question is 90 degree so reflected angle should also be 90 degree. So the reflected ray is opposite to incident ray which means towards the torch.
