Solution

(a)(i) When an object is placed between the optic centre and the focus of a converging lens, the image formed is virtual, erect and magnified as shown in the figure.

(a)(ii) When an object is placed anywhere between the optic centre and infinity of a converging lens, the image formed is virtual, erect, and diminished as shown in the figure.

(b)

S.No Virtual image made by a converging lens Virtual image made by a diverging lens

1 Image is larger than the object Image is smaller than the object
