Is this statement true or false, explain why a thin lens that has a different curvature on each side will have a different focal length on each side.

false

Explanation:

A lens is a device that alters the path of light. A ray of light may diverge or converge depending on the type of lens. The diverging and converging of light takes place due to refraction. Refraction is the phenomenon that causes light to bend when passing through a medium. The bending takes place due to the change in the speed of light in the medium. The distance between the lens and its focal point is known as focal length.

According to the thin lens approximation

In a thin lens the bending of light only takes place once.

The focal length is equal on both sides of the lens.

The focal length with an unsymmetrical radius of curvature is
