Question
A light ray passing through the optical center of a lens ____.
- Does not bend
- Bends towards the normal
- Bends away from the normal
- Bends towards the incident ray
Hint:
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.
