Question

Why convex mirrors are used as vigilance mirrors in shopping malls?

Answer 1

1. A convex mirror is a curved mirror where the reflective surface bulges out toward the light source and the inner surface is polished.
2. Convex mirrors show a large field of view.
3. The image formed by a convex mirror is erect, virtual and diminished.
4. So, the image of a wide range of area is virtually formed by the convex mirror.
5. Thus, convex mirrors provide the ability to see around corners which is enormously valuable when your aim is to protect your shop from thieves.

Therefore, convex mirrors are used as vigilance mirrors in shopping malls.
