Concave lence- A concave lence is a lence that possesses at least one surface that curves inwards.it is diverging lens meaning that is spread out light ray that have been refracted through it.

Convex lens- A convex lens is a converging lens. When parallel ray of light pass through a convex lens the refracted ray converge at one point called principle focus.
