Converging and Diverging Lens

Before I place the diagrams for the two types of lenses, What is a lens?

A lens is a device that causes light to either converge and concentrate or to diverge. It is usually formed from a piece of shaped glass or plastic. Analogous devices used with other types of electromagnetic radiation are also called lenses: for instance, a microwave lens can be made from paraffin wax.

What is a Converging Lens?

A lens that is thickest in the middle, causing parallel rays of light to converge to a focus.



Now, what is a diverging lens?

A lens that is thinnest in the middle and that causes parallel rays of light to diverge.
