Question

A Choose... convex concave  lens is used to converge light.

Answer 1

Answer: A convex lens is used to converge ligtht.

Explanation:

A concave lens is a lens that is thicker on the ends than in the middle. As consequence of this, a concave lens diverges (separate) the rays of light. A concave lens is also called diverging lens.

A convex lens is is thicker in the middle than on the ends. As consequence of this, a convex lense converge the parallel rays that pass through it. A convex lens is also called converging lens.

Answer 2

The answer would be :
A convex lens is used to converge ligtht.

A convex lens is is thicker in the middle than on the ends. As consequence of this it wl reflect light but as the object go near to the mirror, it would be inverted and virtual. So you eill expect an inverted image of you.
