If you are a driver, you are familiar with the rearview mirror. It's a vital part of your car, allowing you to see what's behind you. The rearview mirror is a device that reflects the view behind the vehicle onto the driver's eyes. It is mounted on the windshield and positioned in such a way that the driver can see the reflection of the rear window. In this article, we will discuss the history of the rearview mirror, its types, and how it works.
The History of Rear View Mirror
The rearview mirror has a long and interesting history. The first rearview mirror was invented in 1911 by a man named Elmer Berger. He was a racing driver who was frustrated with having to turn his head to see behind him. Berger attached a mirror to his car's windshield, allowing him to see what was behind him without turning his head. This invention was a game-changer for the automotive industry and helped to prevent many accidents.
However, it wasn't until 1921 that the rearview mirror became standard equipment on cars. The first car to have a rearview mirror as standard equipment was the 1914 Cadillac. The mirror was mounted on the windshield and was adjustable to different angles. Today, the rearview mirror is a standard feature on all cars, and it has saved countless lives over the years.
The Types of Rear View Mirror
1. Manual Rear View Mirror
The manual rearview mirror is the most common type of mirror found in cars. It is typically mounted on the windshield, and the driver can adjust it manually to get the best view of what's behind the car. The manual rearview mirror is simple, reliable, and cost-effective. However, it has some limitations, such as the driver's field of view and adjustability.
2. Automatic Dimming Rear View Mirror
The automatic dimming rearview mirror is a more advanced type of mirror. It uses sensors to detect the brightness of the headlights behind the car and automatically adjusts the mirror to reduce glare. This type of mirror is particularly useful when driving at night, as it reduces the amount of glare that the driver experiences, making it easier to see the road ahead.
How Rear View Mirror Works
The rearview mirror is a simple device, but it works in a complex way. The mirror is made up of two parts: the reflective surface and the support. The reflective surface is made of glass, and it is coated with a thin layer of aluminum, which makes it reflective. The support is usually made of plastic or metal and is designed to hold the mirror in place.
When light hits the reflective surface of the mirror, it bounces back, creating a virtual image of what's behind the car. The image is reversed from left to right, so the driver must adjust to seeing the image in reverse. This is why objects in the mirror appear closer than they actually are. The driver must adjust the mirror to get the best view of what's behind the car.
In conclusion, the rearview mirror is an essential part of any car. It allows the driver to see what's behind the car, making it safer to drive. There are two main types of rearview mirrors: manual and automatic dimming. The manual mirror is the most common type, while the automatic dimming mirror is more advanced. Regardless of the type, the rearview mirror works by reflecting light to create a virtual image of what's behind the car.
