Question

Give notes on 'formation of different types of images by concave lens'.

Answer 1

⠀⠀ ⠀

Concave Lenses :

• When an object is placed at infinity, a virtual image is formed at the focus. The size of the image is much smaller than that of the object.

• When an object is placed at a finite distance from the lens, a virtual image is formed between the pole and the focus of the convex lens. The size of the image is larger than that of the object.
