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
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

The correct option is

b) at a distance larger than the radius of curvature is the right answer

The image created by a concave mirror for an object positioned beyond the centre of curvature or at a distance greater than the radius of curvature is real and inverted, smaller than the object (diminished), and between the focus and the centre of curvature.
