Answer 2

Answer:

There are two types of lenses.

1) Concave lense

2) Convex lense.

Explanation:

Concave lense= A lense made by joining the parts of two spherical surfaces that is thinner in the middle than at the edges. It diverges the incident rays away from its principal axis.

Convex lense= A lense made by joining the part of two spherical surfaces that is thicker in the middle edges. It converges the incident rays towards it's principal axis.
