Real, inverted and enlarged image will be formed in case of:
Concave lens, object placed between focus F & optical centre O.
Convex lens, object placed beyond 2F1.
Convex lens, object placed between F1 and 2F1.
Concave mirror, object placed between pole & focus.
When object is placed between F1 and 2F1 in case of a convex lens, then a real, inverted and enlarged image is formed.
Draw well labelled ray diagrams for image formation by convex lens when
(1) Object is at 2F1
(2) Object between F1 and 2F1
(3) Object between focus F1 and optical centre O.
If an object is placed between F1(first focus) and the optical centre of a convex lens, then the image formed will be
For a converging lens, if the object is placed between 2F1 and F1 the image will be formed.
