Question

Convex lens is always :

• A. tapering at edges
• B. thicker in middle
• C. converges rays at a point
• D. all of the above

Answer 1

The correct option is D all of the above

Answer is D.

A convex lens is a converging lens. When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
A convex lens is thicker at the centre than at the edges.
Hence, all the options are right.
