If the cut part of the hollow sphere is painted from inside, then its outer surface becomes the reflecting surface. This kind of mirror is convex mirror. In a convex mirror, the reflective surface bulges towards the light sources. The main purpose of a convex mirror is to have wider view in a small size mirror. The divergence effect of convex mirror is responsible for this. As a result, diverging mirror is also a name for convex mirror. In this post, we have listed out the applications and uses of convex mirror in the practical world. Read on to find out more.

## Uses of Convex Mirror

• Inside buildings and offices
• Wing mirrors of vehicles
• Special Kind of magnifying glass
• In parking lots
• For security purpose
• In ATM’s
• In auditoriums

## Why Convex Mirror Have These Uses?

The convex mirror always forms a virtual image of the object. Also, the image formed by the convex mirror is smaller than the size of the actual object. Thus, it covers larger area in small mirror. Convex mirrors have a wider view field than concave mirrors and plane mirrors.

## Applications of Convex Mirror in Practical World

### Inside buildings and offices

Large offices, stores, and hospitals use a convex mirror to let people see around the corner so that they can avoid running into each other and prevent any collision. Specially in hospitals, large sized mirrors are used to provide a clear view.

### Wing mirrors of vehicles

Rearview mirrors (wing mirrors) in vehicles such as cars, buses, motorcycles, etc. are compulsorily convex mirrors. These rearview mirrors help the diver to check the vehicles and the traffic behind them. Nowadays, drives attach a special glass with wing mirror called blind spot mirror. This is also a convex mirror.

### Special Kind of magnifying glass

Convex mirrors are widely used for making magnifying glasses. Thus, in order to make a magnifying glass, we place two convex mirrors back to back.

### Use of Convex Mirrors For security purpose

#### In ATM’s

Manufacturers usually place convex mirrors on top end of the ATM machines. Such a unique placement of the mirror helps the withdrawer to check if anyone is standing behind him or observing him. Next time you go to ATM make sure you use this mirror.

#### In auditoriums

You might have seen convex mirrors in auditoriums. The mirrors are placed such that, security guards standing in corners are able to see each and every part of auditorium.
