A lens can be converging (convex) or diverging (concave). The centre of the lens is called the optical centre C. In a ray diagram, a converging lens is drawn as a vertical line with outward facing ...

Difference between Concave vs Convex Lens: Isn’t physics one of those subjects that almost every student is scared of? Well why not, given the complexity of problems and difficulty level of the ...

We compare and contrast concave and convex lenses by drawing ray diagrams. In this Closer Look segment on Lenses, we compare and contrast concave and convex lenses by drawing ray diagrams and ...

These lenses are either convex - converging light, which magnifies an object, or concave, where light diverges making an object smaller. However, this new lens is 40 nm thin on a flat glass surface .
