Which type of mirrors shows a wider area than flat mirrors?

• A. Convex mirrors
• B. Plexiglass mirrors
• C. Concave mirrors
• D. Round mirrors

Answer: (A)

Convex mirrors show a wider area than flat mirrors. The outward-curving surface makes reflected light rays spread apart, so you can see more around you—the field of view is increased. This is why convex mirrors are common for truck side mirrors and security mirrors: they cover more of the surroundings, though objects appear smaller and distances are distorted. In contrast, concave mirrors pull light rays inward, which can magnify images up close but don’t widen the overall viewing area. Plexiglass is a material, not a mirror type, and round mirrors aren’t defined by a specific curvature that guarantees a wider view.
