Convex Lens

Real World Example

Imagine trying to focus sunlight on a piece of paper to start a fire using a magnifying glass. Just like this task requires concentrating light rays to a single point to generate heat, a convex lens does the same by bending light rays that pass through it to converge at a focal point on the other side. The center of the lens is thicker than its edges, which allows it to bend the light inward, much like how the curved glass of a magnifying glass directs sunlight to a specific spot, concentrating its energy to achieve the desired effect.
