- #8In motor vehicles, a convex mirror is attached near the driver’s seat to give him the view of the traffic behind. What is the special function of this convex mirror which a plane mirror can not do?Ans : The special function of a convex mirror is that it creates the image of a distant object that is reduced in size, is upright or erect and always lies within the virtual focal length of the mirror. A plane mirror cannot do this. Also, as the image is formed within the focal length, the image is close to the mirror as well as is small in size, enabling the driver to clearly view the nearer vehicles behind the motor vehicle.
