Answer 2

${\huge{\blue{\underline{\underline{\bf{\red{\mathcal{Answer}}}}}}}}$

A lens is a transmissive optical device which focuses or disperses a light beam by means of refraction. Lenses are made from materials such as glass or plastic, and are ground and polished or molded to a desired shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing.
