Q. If objects appear enlarged and inverted in a rear view mirror, then which type of mirror is used? Answer:
Concave
Notes: A concave mirror can form diminished as well as enlarged images, depending upon the distance of the object from the mirror. The image can be real and inverted or virtual and erect. While a convex mirror always forms a virtual, erect and diminished image, irrespective of the distance of the object from the mirror.
