Which type of mirror is used in automobiles to see the rear side traffic?

Convex mirrors (D) are used in automobiles to see the rear side traffic. These mirrors are curved outward, providing a wider field of view than flat plane mirrors. This allows drivers to see a larger area behind the vehicle, helping to detect other vehicles, pedestrians, and obstacles that might not be visible with a plane mirror. The convex shape of the mirror causes light rays to diverge, which makes objects appear smaller and further away than they actually are. This can help in reducing blind spots and providing a more comprehensive view of the surroundings. The smaller appearance of objects in convex mirrors also means that more area can be observed at a glance, which is crucial for safe driving, especially when changing lanes or reversing. Hence, convex mirrors are essential for enhancing driver awareness and safety on the road.
