Question

Through which of the following points, a ray passing through a centre of curvature and reflected by concave mirror will pass through?
(A) Focus
(B) Centre of curvature(C) Pole
(D) All

Answer 1

answer :- option (B)

we know, when a ray of light passes through the centre of curvature of the concave mirror, it is incident on mirror at 90° . hence, the incident ray concides with the normal and retraces its path.
e.g., reflected ray by concave mirror will pass through centre of curvature.

hence, option (B) is correct.

Answer 2

" B "

Light passing through centre of curvature will retrace its path.

As light falling asleep by passing through center of curvature woll appears to fall on mirror perpendicularly.
