Question

using a ray diagram explain the position relative size and nature of image of an object placed between the F1 and 2F1 of a convex lens....plzz answer me quickly..

Answer 1

Convex Lens Diagram

The image is

Formed beyond 2F2

Real

Inverted

Magnified

Let us consider two rays coming from the object. The ray which is parallel to the principal axis after refraction passes through the lens and passes through F2 on the other side of the lens. The ray passing through the optic center comes out of the lens without any deviation. The two refracted rays intersect each other at a point beyond 2F2. So, when an object is placed between F1 and 2F1 of a convex lens the image is formed beyond 2F2.
