Product description

 

Convex lenses are thicker at the middle. Rays of light that pass through the lens are brought closer together (they converge). 

A convex lens is a converging lens.When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

The distance between the principal focus and the centre of the lens is called the focal length.
