Concave lens curves inward. That means it is thinner in the middle than at the edges. When light passes through a concave lens, the light rays bend so that they spread apart. Concave lenses make objects look smaller than they really are.
Unlike with the convex lens, this ray of light is traced back through the principal focal point on the side where the rays came from.
