Convex Lens

Real World Example

Imagine trying to pour a liquid into a funnel, where the center directs the flow to a point while the edges are thinner and guide the liquid inward. Just like how the funnel gathers and focuses the liquid to a single stream, a convex lens gathers and focuses light rays to a focal point. In this analogy, the thicker center of the funnel corresponds to the thicker center of the convex lens, both serving to converge material—whether it's liquid or light—to a specific point.
