A light ray is incident along the principal axis of a mirror after reflection ______.

A

retraces its path

B

passes through centre of curvature

C

makes zero angle with the normal

D

All the above

Text Solution

Verified by Experts

The correct Answer is:
D
The light ray which is incident along the principal axis of a mirror falls normally on the mirror, and hence, it retraces its path.

From the figure it is clear that it passes through the centre of curvature. As the line passing through the centre of curvature is perpendicular to the mirror, the angle made by the light ray with the normal is zero.
