Question

Function of Convex mirror

Answer 1

convex mirror used asa side glass of automobiles because it gives wide image of object

Answer 2

A convex mirror is also known as diverging mirror or the fish eye mirror. The reflective surface of the convex mirror bulges towards the light source. Convex mirrors reflect the light falling on them outwards. The image of the object formed by a convex mirror is always virtual. Also the image formed is smaller than the actual size of the object. Thus, major uses of convex mirror are in the areas where bigger objects are to be viewed easily and in smaller size. Here we will discuss about most vital and common 10 uses of convex mirrors. Some of them are also described with the working and reason of use of convex mirror with that particular application.

10 Uses Of Convex Mirrors:

Some of the most important and wide 10 uses of convex mirrors are described below with a little explanation with them as well:

1. Convex mirrors are used inside buildings:

Large hospitals, offices or stores sometimes make use of convex mirrors in order to let people see what is around a corner to avoid people running into each other and prevent minor/major collisions.

2. They are used in sunglasses:

Convex mirrors are also used in making lenses of sunglasses. This is done to help reflect the light of sun away from the eyes of the person wearing the sunglasses.

3. Convex mirrors are used in vehicles:

They are used as a rear view mirror in vehicles because the mirror can diverge a beam of light and makes a virtual image. And as the focal length and radius of curvature of the convex mirror are virtual the image is always produced up the right way and that too smaller in size than the actual size of the object. So the mirror is able to give a wide view of the field.

4. Use in magnifying glass:

Two convex mirrors are placed back to back in order to make a magnifying class.

5. Use of convex mirror in securities:

convex mirrors are placed near ATM’s so as to allow the bank customers to check if someone is behind them. This is a measure of security taken which helps in keeping customer’s using ATMs safe from robberies of cash withdrawals or other valuables or even their cards along with the pin number. This also keeps the identity of ATM user’s secure.

6. Convex mirrors use also used as street light reflectors because they are able to spread light over a bigger area.

7. They are also used for inspection purposes for places where it is difficult to reach. For this, the mirrors are mounted on an appropriately sized rod and are extended with lights under the object that is to be viewed, common examples for this are appliances or car repair, clocks etc.

8. They are also put on corners of roads so that you can see any cars coming to avoid collisions.

9. They are also used in telescopes.

10. Another use of convex mirrors is as ceiling dome mirrors.
