Question

What are the properties of the image formed by a rear-view mirror?

• A. It forms a real, inverted and diminished image.
• B. It forms a virtual, erect and diminished image.
• C. It forms a real, inverted and magnified image.
• D. It forms a virtual, erect and magnified image.

Answer 1

The correct option is B It forms a virtual, erect and diminished image.

A convex mirror always forms a diminished, virtual and erect image irrespective of the object position. Also, it allows more light to fall because of the nature of its curvature. Hence, it has more field of view. Thus, a convex mirror is used as a vigilance mirror.
