Why are convex mirror used as reflectors in street light?

Convex mirrors are used as reflectors in street lights because they provide a wide field of view, allowing light to be distributed over a larger area. Their curved shape helps to direct and spread the light more effectively, reducing shadows and enhancing visibility for drivers and pedestrians. Additionally, convex mirrors can minimize glare, making them safer for nighttime use. This combination of features makes them ideal for illuminating streets and public spaces.
