Answer 1

Answer:

Lenses are classified by the curvature of the two optical surfaces. A lens is biconvex (or double convex, or just convex) if both surfaces are convex. If both surfaces have the same radius of curvature, the lens is equiconvex. Alens with two concave surfaces is biconcave (or just concave).

Uses of lens :
