Answer 1

A convex lens is thicker in the middle than on the edges.

Step-by-step explanation:

Convex lens are converging lens with its edges curved outwards. When light rays travels through a convex lens; they merge and focus at the principal focus, bend light rays inwards the optical axis, travel parallel to the principal axis..

A convex lens can be made to produce real or virtual image. The convexity of the lens in the human eyes helps it to focus the light on the retina. Convex lens are widely used for magnification purposes in telescopes, microscopes, camera lens etc
