How do convex mirrors compare to flat mirrors?

Answer: B — They show a wider area

Convex mirrors differ significantly from flat mirrors in their ability to reflect light and create images. The primary characteristic of convex mirrors is their outward curvature, which allows them to capture a larger field of view compared to flat mirrors. This wider area is particularly beneficial in situations such as vehicle side mirrors, where it is crucial to see as much of the surroundings as possible. While flat mirrors provide a more accurate reflection of the objects in front of them, they offer a limited perspective, focusing on a narrower field. In contrast, convex mirrors spread the reflected light over a larger area, resulting in a more extensive view of the environment. This makes them effective for safety applications, allowing drivers to see more of the traffic behind and beside them. Therefore, the ability of convex mirrors to show a wider area than flat mirrors is a key advantage, especially in scenarios requiring increased awareness of surroundings.
