alleryStart learning →A concave mirror forms an erect image only when the object is placed
Abeyond the centre point
Bwithin its focal length
Cexactly at its focus
Dat the curvature centre
Answer & Solution
Correct answer: B. within its focal length
1. Beyond F a concave mirror gives real, inverted images.
2. Only when the object is nearer than the focus do reflected rays diverge.
3. Their backward extensions then give a virtual, erect, enlarged image.
