Answer:
(a) Convex Mirror.
Explanation:
Convex mirror is used to see the rear view of vehicles.
The reasons are:
- It always produces a diminished image of an object, so the field of view is always wider than that of the images produced by the other mirrors.
- The image produced by the convex mirror is always erect, so that the vehicles moving behind seem erect.
The plane mirror forms image with the same size as the object therefore it can not be used as rear view mirror.
The convex mirror forms magnified image therefore it can not also be used for the rear view mirror.
