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.
