Question

Which describe the image formed by an object on the center of curvature? Check all that apply.

Answer 1

The image formed by a concave  mirror with the object placed at the center of curvature is real inverted and formed at the center of curvature. Using the ray diagram a ray from the top of the object to the mirror through f then reflected parallel to the principal axis,then the ray through the center of curvature reflected through the same point both intersect at a plane through center curvature and perpendicular  to the principal axis. The point of intersection forms the top of the image and the center of curvature forms the bottom. Therefore, the correct choices are : real and inverted

Answer 2

The answer is real and inverted. And is not smaller or larger because they both have the same size. :)
