A convex mirror, also known as a diverging mirror or a safety mirror, is a curved mirror with a reflective surface that bulges outward. Unlike a flat or concave mirror, a convex mirror curves outward and causes light rays to diverge, resulting in a wider field of view. Convex mirrors are commonly used for safety and surveillance purposes.

One of the primary advantages of convex mirrors is their ability to provide a broad, panoramic view of an area. Due to their shape, they have a wider field of vision compared to flat mirrors, allowing users to see a larger area in a single glance. This makes them particularly useful in parking lots, road intersections, and other areas where a wide field of view is crucial for safety.

Convex mirrors are known for their ability to eliminate blind spots. They can reflect light from different angles, increasing visibility and reducing the chances of accidents. This makes them an effective tool for enhancing road safety and preventing collisions, as they provide drivers with a wider perspective of the surrounding environment.
