A rectangular convex mirror is a specialized type of convex mirror with a rectangular shape, as opposed to the more common circular or spherical convex mirrors. It shares the same optical properties as other convex mirrors, but its rectangular design offers certain advantages in specific applications.

The curvature of the rectangular convex mirror causes light rays to diverge outward after reflection, just like other convex mirrors. This results in a smaller and virtual image that appears further away from the mirror surface than the actual object.

The rectangular shape of the mirror makes it particularly useful in situations where a wider field of view is required in a specific direction. For example, rectangular convex mirrors are often used in traffic and road safety applications, such as at intersections or sharp bends, to improve visibility for drivers and pedestrians.

In industrial settings, rectangular convex mirrors can be strategically placed to enhance visibility around corners, aisles, or blind spots, increasing safety and minimizing the risk of accidents.

The rectangular shape also allows for more flexible mounting options, making it easier to install the mirror in certain spaces where circular convex mirrors may not be as practical.
