Which convex mirror is used as the driver’s mirror? What is its drawback?

Hint:To solve this question we should know about:
Convex mirror: A convex mirror has a curved reflective surface that bulges out towards the light source. This protruding surface reflects light outwards rather than focusing it.
So, we first go through its property and then we solve our question.

Complete step by step solution:
Property of image formed by convex mirror:
The image is always upright and imaginary.
The image has been greatly reduced in size or has been reduced to a point size.
It is always made up of F and P.
The image and the object are on different sides of the mirror.
A driver can see a huge portion of the traffic behind him with a convex mirror. The image formed by a convex mirror is much smaller than the thing. Convex mirrors are utilized as rear view mirrors in vehicles because of this.
So, now it will be clear why we use this mirror.
Disadvantage of using convex mirrors as side mirrors: The disadvantage of employing convex mirrors for automotive rearview mirrors is that they give the impression that the objects are further away than they are. This is why the mirrors are marked with the phrase "Objects in mirror are closer than they look."

Note:
Application of Concave mirror: Concave mirrors are utilized in a variety of applications, including searchlights, shaving mirrors, satellite dishes, and more. The collimation and concentration of light rays is a property of these mirrors. Reflectors are concave mirrors in torches and headlights.
