Question

A light ray passing through the optical center of a lens ____.

  1. Does not bend
  2. Bends towards the normal
  3. Bends away from the normal
  4. Bends towards the incident ray

hintHint:

A light ray passing through the optical center passes through the center without bending i.e. it travels through the optical center perpendicular to the lens’s curved surface.

The correct answer is: Does not bend


    A light ray passing through the optical center of a lens does not bend.
    • A light passing through the optical center of the lens does not deviate.
    • It is passing in the perpendicular direction and the emerging ray travels in the same direction.
    • Thus, the angle of the incident ray and the angle of the emerging ray both becomes 0
