Question

Why does a ray passing through the center of curvature of a concave mirror gets reflected along the same path after reflection?​

Answer 1

Answer:

Explanation:

A ray of light passing through the centre of curvature of a concave mirror retraces its path (gets reflected along the same path), because as the ray of light passes through centre of curvature of a concave mirror it strikes the mirror along the normal i.e. it incidences on to the mirror at 90 degree.

Answer 2

Answer:

because centre of curvature is the normal line for the light rays.

Explanation:

centre of curvature is zero degree.

so, angle of incidence is equal to angle of reflection is equal to zero degree.

so, it retraces the path
