LENS

Lens are two reflective surfaces joined together. There are two types of lenses: diverging lens and converging lens.

3 Types of Converging Lenses and Diverging Lenses

Converging lenses collects light and lets them converge in one point.

Diverging lenses scatters light, thus the word.

Note: If the distance of the object is infinite, the image formed is a point.

Equation:

Sign conventions:

Note: Converging Lens are positive lens whereas diverging lens are negative lens.
