The image formed by a concave mirror is observed to be virtual, erect and larger than the object. Where should the object be positioned?
A
Between focal length and centre of curvature
B
At center of curvature
C
Beyond center of curvature
D
Between the pole and principal focus
Correct Option:
D
Explanation
A concave mirror forms a virtual, erect and enlarged image only when the object is placed between the pole P and the principal focus F. The reflected rays diverge, and their backward extensions meet behind the mirror. At other usual object positions, a concave mirror produces real and inverted images.
