Are Car Rearview Mirrors Concave or Convex?
1 Answers
Car rearview mirrors are convex mirrors. Convex mirrors are suitable for car rearview mirrors: The image formed by a convex mirror is upright, reduced, and virtual. The external viewable range from a convex mirror is larger than that of a flat mirror of the same size. Therefore, the mirrors mounted on the exterior of a car's driver compartment are convex, allowing the driver to see a wider area behind the car when reversing, enhancing safety and reducing the likelihood of hitting people or objects. Concave mirrors are not suitable for car rearview mirrors: Because concave mirrors reduce the field of view, which contradicts the driver's need for visibility. Concave mirrors narrow the driver's rearview field of vision, making it harder to observe a broader surrounding environment and thus compromising driving safety.
