Concave And Convex Lenses: Image Formation

Spherical lenses are the lenses formed by bounding two spherical transparent surfaces together. In general, there are two types of spherical lenses. So, lenses formed by binding two spherical surfaces bulging outward are known as convex lenses while the lenses formed by binding two spherical surfaces such that they are curved inward are known as concave lenses. This is one of the basic difference between concave and convex lenses.

Convex lenses are also known as converging lenses since the rays converge after falling on the convex lens while the concave lenses are known as diverging lenses as the rays diverge after falling on the concave lens. In this article, we will learn about image formation by concave and convex lenses.
