cóncavos
Cóncavos is a term used in geometry and optics to describe a shape or surface that curves inward. In geometric terms, a concave shape is the opposite of a convex shape. Imagine a cave entrance; the opening of the cave is concave. In optics, concave lenses and concave mirrors are used to manipulate light. A concave lens, also known as a diverging lens, causes parallel rays of light to spread out or diverge. A concave mirror, also known as a converging mirror, focuses parallel rays of light to a point called the focal point. The curvature of a concave surface can be described mathematically by its radius of curvature. A smaller radius of curvature indicates a more pronounced inward curve. The term can also be used in a more general sense to describe any object or area that is hollowed out or indented. For example, a concave dish is one that curves inward to hold something. Understanding concavity is important in various fields, including physics, engineering, and design, as it influences how objects interact with light, liquids, and forces.
