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 ...

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 ...

In a ray diagram, a concave lens is drawn as a vertical line with inward facing arrows to indicate the shape of the lens.

Mirror is a reflecting surface or a polished metal that forms images. It works on the principle of reflection of light. When a man stands in front of the mirror, light from all parts of the body is ...
