Why do we prefer a convex mirror as a rear-view mirror in vehicles?

 

Answer

A convex mirror is used as a rear-view mirror because
the image provided by a convex mirror is

  • Erect - Hence, the image produced to the driver is not inverted, it’s right side is up.
  • Diminished - Hence, the image produced is much smaller than the actual size of the object. This helps in providing a wider field of view .
