Answer:

please mark me as brainliest and follow me

Explanation:

A concave mirror gives an erect and enlarged image of an object held between pole and principal focus of the mirror

Convex mirror always produces virtual, erect and diminished image of the objects. The image formed by the convex mirror is highly diminished which enables the driver to view much larger area of traffic behind him.

Answer 2

concave mirror produce an erect and enlarged image of an object.

Convex mirrors are commonly used as rear-view (wing) mirrors in vehicles because they give an erect, virtual, full size diminished image of distant objects with a wider field of view. Thus, convex mirrors enable the driver to view much larger area than would be possible with a plane mirror.
