A convex mirror is used as a rear view mirror in vehicles because___.
convex mirror has a wider field of view.
A convex mirror shows diminished images and objects appear to be closer than they actually are. So clearly, the size of the image is not equal to the size of the object and also the distance between the image and the mirror is not equal to the distance between the object and the mirror. Secondly, a convex mirror has a larger field of view i.e it can capture a larger part of the surrounding and this property makes it apt to be used as a rear view mirror in vehicles.
