Why is a convex lens called a converging lens and a concave lens a diverging lens? [3 MARKS]

Solution

If parallel rays of light fall on a convex lens they converge when passing through and meet at a point on the other side. That's why the convex lens is known as a converging lens.

If parallel rays of light fall on a concave lens they diverge as they pass through the lens never to meet at a point. That's why we call them diverging lens.
