What is a characteristic of a converging lens?

A converging lens, also known as a convex lens, is characterized by being thicker in the middle and thinner at the edges. This shape allows the lens to converge (or focus) light rays that are entering it. When parallel rays of light pass through a converging lens, they are refracted inward and meet at a focal point on the opposite side of the lens. This fundamental property makes converging lenses essential in various optical applications, such as cameras, magnifying glasses, and corrective eyewear for hyperopia.

The other options describe different types of lenses or their functionalities incorrectly. A lens that is thick at the edges and thin in the middle would instead be a diverging lens, which spreads light rays apart rather than converging them. A lens with uniform thickness would not have the optical properties necessary to focus light. Finally, a statement suggesting that a converging lens cannot focus light contradicts the very definition of its function.
