Question

why does the ray passing through the centre of curvature of a concave mirror retraces it's path.

Answer 1

Answer:

The reason for light falling on the centre of curvature gets reflected back along the same path is due to the angle of incidence and the angle of reflection lie along the normal for a concave mirror. ... Hence, the angle of reflection tends to zero degree, thus the ray of light retraces its path.
