Expert Answer:

Dear student
The rear view mirror used in cars is a convex mirror.
It forms a virtual, erect & diminished images of the objects behind the vehicle.
Since the images formed are diminished in size irrespective of the size & the location of the objects with respect to the mirror behind, there is a caution note written on the mirror that objects seen from behind are closer than they appear in the mirror. The diminished images as seen in the mirror give an illusion of the objects being very far away.
We hope that resolves your query
