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 :

Yes, the statement is correct.


To get the magnified virtual image, the object is to be placed between the optical centre of the convex lens and the focus F1 of the convex lens. The image formed will be virtual and magnified.



However, for obtaining a magnified real image, the object should be placed in between F1 and 2F1 of the convex lens.
