A rear-view mirror is called a rear-view mirror because its purpose is to help the driver see what is happening behind the vehicle.
Step-by-step explanation:
A rear-view mirror is called a rear-view mirror because its purpose is to help the driver see what is happening behind the vehicle. It is typically mounted on the inside of the vehicle, near the windshield, and angled so that it reflects light from the back of the vehicle to the driver's eyes. This allows the driver to see if there are any objects, vehicles, or people behind them without having to turn their head.
The rear-view mirror is usually a flat mirror that produces an upright image, which means that the reflected image appears the same way as the actual object behind the mirror. This makes it easier for the driver to interpret and understand what they are seeing in the mirror.
