Which mirrors show a wider area than flat mirrors?

Bar-shaped mirrors
Flat mirrors
Convex mirrors
Rear-view mirrors

The correct answer is: Convex mirrors

Convex mirrors are designed with a curved surface that bulges outward, which allows them to capture a broader field of view compared to flat mirrors. This curvature causes light rays to diverge after reflecting off the surface, enabling the driver to see more of the surroundings. As a result, convex mirrors are particularly useful in situations like changing lanes or parking, as they reduce blind spots and help in monitoring the environment around the vehicle. While bar-shaped mirrors can offer some enhanced visibility and rear-view mirrors are essential for safe driving, convex mirrors specifically provide an increased scope of the area, making them more effective for wide-angle viewing. Flat mirrors, on the other hand, reflect images in their true size but do not offer the same wide-angle perspective that convex mirrors do.
