Concave Lens

Real World Example

Imagine you're trying to carry a large tray of drinks through a crowded room, and you have to be careful not to spill anything. Just as you navigate this tray by strategically moving around obstacles, a concave lens directs light in a similar way due to its shape. The way you must balance the tray to keep it stable, with the weight focused on the edges rather than the center, mirrors how a concave lens is shaped with a center thinner than its edges; this shape causes light rays to diverge outward, much like the drinks spreading out if the tray tilts.
