Question

why a light ray passing through centre of curvature traces the same path ??

plz explain accurately ​

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. Hence the incident ray coincides with the normal

Answer 2

yes it reflects back in the same pathway and creats zero degree angle between it.
