Question

concave lens never form real image of objects
give reason

Answer 1

No,it is not possible to form a real image using a concave lens,concave lens always forms a virtual image and never forms a real image.

This is because of the fact that it always diverge the light rays and never converge them so light rays passing through it will never actually meet and no real image will be formed.

Answer 2

a concave lens usually diverges the rays... so the refracted rays actually never meets. but they seems to meet at one point inside the mirrors(extended light rays intersects) so it always forms virtual and erected images only..

hope it helps you.. so plz give a big heart and mark as brainlist..
