Vehicle Rear View Mirror Type Explained
Rear view wing mirrors in vehicles are designed to provide the driver with the widest possible field of vision to ensure safety. They help monitor traffic behind and alongside the vehicle.
Mirror Properties for Rear View Application
The choice of mirror depends on its optical properties:
- Concave mirrors produce magnified or diminished images, which can be misleading or limit the view.
- Plane mirrors provide a true-to-size image but offer a very limited field of view.
- Convex mirrors always form images that are:
- Virtual (cannot be projected on a screen)
- Erect/Upright (same orientation as the object)
- Diminished (smaller than the object)
Why Convex Mirrors are Used
Convex mirrors are ideal for rear view wing mirrors because the diminished size of the image allows them to reflect light from a much wider area compared to plane or concave mirrors. This expansive field of view is crucial for drivers to see more of the road behind and to the sides, enhancing situational awareness and reducing blind spots.
Therefore, convex mirrors are used as rear view wing mirrors in vehicles.
