comments. 1.concave lense 2.convex lense​

Answer 1

Explanation:

A concave lens is a type of lens that diverges a straight light beam coming from the source to a diminished, upright, virtual image is known as a concave lens.

A convex lens is also known as a converging lens. A converging lens is a lens that converges rays of light that are traveling parallel to its principal axis.

Answer 2

Concave lens

A concave lens is a type of lens that diverges a straight light beam coming from the source to a diminished, upright, virtual image is known as a concave lens. It can form both real and virtual images. Concave lenses have at least one surface curved inside.

Convex lens

A convex lens is also known as a converging lens. A converging lens is a lens that converges rays of light that are traveling parallel to its principal axis. They can be identified by their shape which is relatively thick across the middle and thin at the upper and lower edges.
