Question

Why does the driver prefer to use a convex mirror as a rear-view mirror?

Answer 1

Hint: Here, in this question we have asked about the convex mirror. In order to solve this you have to know the concept of convex mirror. Also remind us of the uses of a convex mirror and remember that when the object is at infinity or we can say very far away from the mirror, the image formed is upright and located at the focal point of the mirror.

Complete answer:
As we know that the convex mirror forms a virtual, erect and diminished image irrespective of the distance of the object therefore the drivers prefer to use a convex mirror as rear-view mirror.
Also the large area of the traffic or the vehicles coming or running behind the driver can easily be seen through the convex mirror. As the convex mirror always forms the image that is virtual and smaller in size than the actual object.
Additional information:
These convex mirrors are more often used in big hallways of hospitals, buildings, hotels, etc. They are also used in the blind turns on the roads which helps the drivers or bikers at the curves and turns where there is lack of visibility.
Convex mirrors are also used for making magnifying glasses. Two convex mirrors are placed back to back in order to make a magnifying glass. Convex mirrors are also used for security purposes in various places. They are placed at the ATMs to help the customer, as if there is someone behind them, they can check.

Note: You have to understand the difference between the convex and concave mirror as we discuss above that the convex mirror forms a diminished and erect image of the object while on the other hand the concave mirrors form a magnified and inverted image of the object. So, don’t get confused between the two mirrors.
