Question

An incident ray which is passing through the center of curvature of a concave mirror
​

Answer 1

Answer:

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.
