Question

When the object is kept at the centre of curvature of a concave mirror, the image size is ________________ the object size.

Answer 1

If an object is placed at the center of the curvature(C) of a concave mirror, light rays meet to form an image that is

1. a real, inverted image, and it is formed at the same position(at C)
2. same size as that of the object.

Hence, When the object is kept at the center of curvature of a concave mirror, the image size is equal to the object size.
