For a concave mirror, when the object is exactly at the centre of curvature, the image formed is
Aat F, small and inverted
Bat C, same size and inverted
Cbehind mirror and virtual
Dfar away at the infinity
Answer & Solution
Correct answer: B. at C, same size and inverted
1. Object at C: the ray through C retraces, and the parallel ray reflects through F.
2. These reflected rays meet again at C.
3. So the image is at C, same size, real and inverted.
