A concave lens is any lens that has an inward curve in the middle. In other words, the edges of thelens are thicker than the middle. This causes light that enters thelens to spread out, or diverge. In effect, this makes images appear smaller when viewed through aconcave lens.
A convex lens is a converging lens. When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus. The distance between the principal focus and the centre of the lens is called the focal lengt
