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

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 ...

When people look into a mirror, they see an image of themselves behind the glass. That image results from light rays encountering the shiny surface and bouncing back, or reflecting, providing a ...
