Given a concave mirror, rays of light originating from the center of curvature reflect off the mirror and focus at
A) infinity.
B) the center of curvature.
C) 2 R from the mirror.
D) the focal point.

Question

Quizplus · Accepted Answer

When rays of light originating from the center of curvature of a concave mirror reflect off the mirror, they converge back at the center of curvature. This is because the center of curvature is located at a distance of 2f (twice the focal length) from the mirror, and rays originating from this point reflect back onto themselves.

Given a Concave Mirror, Rays of Light Originating from the Center
