What kind of mirror is a car's rearview mirror?
1 Answers
Car rearview mirrors are convex mirrors, which have a light-dispersing effect, providing a wider field of vision compared to flat mirrors and enhancing safety. Rearview mirrors can be categorized by installation location into: exterior rearview mirrors, lower rearview mirrors, and interior rearview mirrors. By purpose, the exterior rearview mirrors show the rear sides of the car, the lower rearview mirrors display the area in front and below the car, and the interior rearview mirrors reflect the rear of the car and the interior conditions. The functions of car rearview mirrors include: 1. Observing passengers in the back seat through the central rearview mirror, especially when there are children; 2. Estimating the distance between vehicles via the central rearview mirror—when the rear car's front wheels are just visible in the mirror, the distance is about 13 meters; when the grille is visible, it's approximately 6 meters; and when the grille is just out of sight, the distance is about 4 meters.
