Question

A convex lens of focal length 20 cm can produce a magnified virtual as well as real image. Is this a correct statement ? If yes, where shall the object be placed in each case for obtaining these images ?

Answer 1

Yes, a convex lens of focal length `20 cm` can produce a magnified virtual as well as real image. The statement is correct. For magnified virtual image, the object must be held at a distance less than `20 cm` from the lens. For magnified real image, the object must be held at a distance between 20 cm and 40 cm from the lens.
