In each of the following cases, where must an object be placed in front of a convex lens so that the image formed is

(a)at infinity,

(b)of same size as the object,

Solution:

(a) At focus,

Object must be placed at the focus of a convex lens so that the image is formed at infinity.

(b) At 2F,

Object must be placed at a distance of twice the focus of a convex lens so that the image is of the same size as the object.
