A convex mirror, also known as a diverging mirror or a fish-eye mirror, is a curved mirror with a reflective surface that bulges outward. It differs from a flat mirror or a concave mirror in that it curves outward, causing light rays to diverge when reflected. Convex mirrors have a wide range of applications, particularly in areas where a broader field of view and increased safety are essential.

One of the key features of a convex mirror is its ability to provide a wider field of vision compared to flat mirrors. Due to its curved shape, a convex mirror reflects light in a way that allows a larger area to be visible in the reflection. This makes convex mirrors ideal for use in areas where visibility is critical, such as parking lots, road intersections, and blind spots.

Convex mirrors are widely used for safety and surveillance purposes. They help eliminate blind spots and provide a panoramic view, enabling drivers, security personnel, and others to have a better understanding of their surroundings. In traffic management, convex mirrors are often placed strategically to enhance safety by improving visibility and reducing the risk of accidents.
