alleryA real image of an object can be formed by:
AConvex lens with object beyond F
BConcave lens
CPlane mirror
DConcave mirror with object inside F
Answer & Solution
Correct answer: A. Convex lens with object beyond F
1. Real images need converging rays that actually meet.
2. A convex lens with object beyond F produces converging refracted rays.
3. These meet on the other side to form a real image.
4. Concave lens always gives virtual images.
5. Plane mirror always gives virtual images.
6. Concave mirror with object inside F gives a virtual image.
7. So only option A makes a real image.
