Question

A ray ACB is incident on a spherical mirror whose centre of curvature is C. In which direction will it reflect?

Answer 1

The reflected ray will retrace the incident ray because the incident is coming through the principal axis.

Answer 2

Explanation,

Any ray of light that is incident on a spherical mirror whose centre of curvature is C, it will retrace its path. It means that light will reflect back in the same path as it is coming. It is one of the rule while drawing ray diagrams.

Hence, the light will reflect in the direction of ACB.
