Which type of mirror provides a wider field of view but can make objects appear farther away?

• A. Convex mirrors
• B. Flat mirrors
• C. Concave mirrors
• D. Rearview mirrors

Answer: (A)

Convex mirrors bulge outward, which causes reflected light to spread apart. Because the rays diverge, your brain extends them backward to form a virtual image that is smaller than the actual object and appears farther away. This shrinking of the image lets the mirror cover a wider angle, giving you a broader field of view— exactly what you want for visibility around you in a vehicle or at intersections. The trade-off is that objects look smaller and farther away, so distance judgment is reduced. Flat mirrors reflect with no change in size or perspective, so they don’t widen the field of view. Concave mirrors can magnify objects or produce different image distances depending on where the object is relative to the focal point, but they don’t reliably provide the wider field of view that convex mirrors offer. Rearview mirrors describe usage, not a specific curvature, and they can be flat or convex; the one that broadens visibility is the convex type.
