(1) A convex lens is known as a converging lens.
​

Answer 1

Explanation:

When the rays of light coming parallel to principle axis after refraction through the lens passes through a point called focus, since it converge all the ray at one point, that is why it is said to be converging lens.

Answer 2

Answer:

A convex lens is called a converging lens because when parallel rays of light fall on such a lens, the rays will get refracted and after refraction they will converge at a focal point at a certain distance away from the lens.
