What happens to the size of the image when the object is brought from infinity closer to (a) concave lens (b) convex lens ?

Text Solution

Verified by Experts

(a) When the object is brought from infinity closer to a concave lens, the image size slowly increases, but the size of the image is diminished when compared to size of object.
(b) When the object is brought from infinity closer to a convex lens, the image size increases, after a certain position, the image size is magnified when compared to the size of the object.

To find the image - distance for varying object - distance in the case of a convex lens, a student obtains on screen a sharp image of a bright object placed very far from the lens. After that the gradually moves the object towards the lens and each time focuses its image on the screen.
