Answer:

The lens is convex lens.

The light ray parallel to the principle axis will pass through the focus.

Explanation:

1. A convex lens can be regarded as made of a very large number of portions of triangular prisms.

2. The bases of these prisms are towards the central thicker portion of the lens.

3. A ray of light passing through a prism bends towards its base.

Hence, a convex lens converges the light rays.

Concepts:

A lens having both spherical surfaces puffed up outwards is called a convex lens.

2. It is thicker in the middle than at the edges.

3. A convex lens is also called a converging lens.
