Generation

A **converging lens** (convex) is thicker in the middle than at the edges and bends incoming parallel light rays inward so they meet at a focal point—this is why it can focus sunlight to a point or make objects appear magnified when used as a magnifying glass. A **diverging lens** (concave) is thinner in the middle than at the edges and spreads incoming parallel light rays outward, making them appear to come from a focal point behind the lens—this is why objects viewed through it appear smaller. The key difference is that converging lenses bring light together while diverging lenses spread light apart, which is why they're used in different applications like cameras (converging) versus correcting nearsightedness (diverging).
