Concave and convex lenses are also called _____ and _____ lenses respectively.

The correct answer is: Diverging, converging

Concave and convex lenses are also called diverging and converging lenses respectively.

• The concave lens diverges the rays and does not allow the rays to meet.
• The convex lens converges the rays that pass through them and focuses the rays at the focus.
• Thus, the concave lens is the diverging lens and the convex lens is a converging lens.
