Question

Which can form real and virtual image ? Why?

Answer 1

concave mirror and convex lens can form both virtual and real image

Answer 2

A diverging lens (one that is thicker at the edges than the middle) or a convex mirror forms a virtual image. ... Such an image will be magnified. In contrast, an object placed in front of a converging lens or concave mirror at a position beyond the focal length produces a real image.
