Question

why do we prefer a mirror as a rear view of mirror in vehicle

Answer 1

We prefer a convex mirror as a rear view mirror in a vehicle as it always gives an erect image. It also provides a wider frame of view to the driver.

Answer 2

Explanation:

We prefer a convex mirror as a rear-view mirror in vehicles because it gives a wider field of view, which allows the driver to see most of the traffic behind him. Convex mirrors always form a virtual, erect, and diminished image of the objects placed in front of it.
