Question

The real image formed by a concave mirror is smaller than the object if the object is:

(a) between centre of curvature and focus
(b) at a distance greater than radius of curvature
(c) at a distance equal to radius of curvature
(d) at a distance equal to focal length

Answer 1

 at a distance greater than the radius of curvature
The real image formed by a concave mirror is smaller than the object if the object is placed at a distance greater than the radius of curvature.
