A: We have to use some basic formula here
- Lenses are of two types converging and diverging. The light gets refracted through a lens.
- A converging lens is capable of converging the light rays that fall on it to a point. It is also known as a convex lens.
- A diverging lens will diverge all the rays that fall on it and is called a concave lens.
