A convex mirror is a type of mirror that has a curved, outwardly bulging surface. This type of mirror is often used in public places such as shopping malls, parking lots, and roadways, because it allows a wide field of view. When placed on the side of a car, it can help the driver see cars that might be in their blind spot. Convex mirrors are also sometimes used in interior design to make a room appear larger. However, because of the curvature of the mirror, objects in a convex mirror will appear smaller and farther away than they actually are, which can make it difficult to judge distances accurately.
Convex mirrors are used on roads to provide a wider field of view for drivers, especially at intersections and on roads with blind spots. They are typically mounted on the sides or corners of vehicles, such as buses and trucks, and on traffic signals. They are also used at intersections, driveways, and other locations where visibility is limited.
Convex mirrors help drivers see other vehicles, pedestrians, and other objects that may be in their blind spot or approaching from the side. They are particularly useful for detecting vehicles approaching from the rear, as they can provide a clearer view of the road behind the vehicle.
Overall, convex mirrors help to improve safety on the road by providing drivers with a better view of their surroundings and helping them to anticipate potential hazards.
