A convex mirror is a curved mirror that bulges outward, causing light rays to diverge. This type of mirror reflects images in a way that makes them appear smaller and farther away than they actually are. Convex mirrors are commonly used in places like parking lots and on the sides of roads to provide a wider field of view, helping drivers see around corners and obstacles. These mirrors are often made of glass or plastic and have a reflective coating on the back. Because of their unique shape, convex mirrors can capture a larger area compared to flat mirrors, making them useful for security and safety purposes in various settings, including stores and highways.
