Question

A ray of light passing through____retraces its path​

Answer 1

Answer:-

A ray of light passing through centre of curvature retraces it's path.

Explanation:-

Any ray of light passes through centre of curvature retraces it's path because the surface of mirror is perpendicular to that ray and the angle of reflection will be 0.

As we know that according to 2nd law of reflection, angle of incidence must be equal to angle of reflection. The ray of light falling on surface of mirror will deviate at angle of 0° which would be same like that of incident ray.

Hence the ray of light passes through centre of curvature retraces it's path.
