A convex mirror is also commonly called as a curved mirror. Where the reflective surface of a concave mirror bulge towards the inward direction, in case of a convex mirror it bulges in the direction where the light source is located.
If you have to find which one is a convex mirror out of the different types of mirrors like a plane mirror, concave mirror, and convex mirror, then it can be done just by looking at the size of the image.
A convex mirror is given the name of a "diverging mirror". It is because of the behavior of the mirror that makes light rays to diverge upon reflection. By this, it means that when a light ray is directed on this mirror, it enables the originally parallel light rays that form the beam to deviate/diverge after hitting the reflective surface of the convex mirror.
In a convex mirror, there is a point where light rays received from all the different directions meet. This helps in creating a focused beam. This point is referred to as the “focal point” or the focus. There is another term called “focal length” that determines the distance between the front of the convex mirror and the focal point.
There are different functions performed by a convex mirror that makes it useful in a variety of applications. Let us see some of the important uses of convex mirrors.
Safety and efficiency are the two most essential requirements when you drive on the road. By providing a good overview to drivers about the rear and side view of the roads, and surroundings, help drivers to foresee risky situations and avoid accidents. Convex mirror is one of the important things that offer a clearer rear view of the road to ensure maximum safety at all the time.
Convex mirrors are kept close to the ATM or automated teller machine to permit the customers to figure out whether someone is standing behind him. This is used to ensure the security of the customers while they use an ATM. It ensures safety from the theft of withdrawals of cash or any other precious item. Also, it keeps the identity of the machine user safe and secure.
Some mobile phones come with a selfie camera built into them that aids users to capture a self-portrait shot.
Large hospitals, hotel, schools, offices, apartment buildings or stores use convex mirrors to allow people to view what goes around a corner. This helps in avoiding minor or major collisions.
Convex mirrors are used in developing a sunglass lens. The overall purpose is to reflect the sunlight away from the person who wears these glasses.
Two convex mirrors when placed next to each other can form a magnifying glass.
Convex mirror is used as a street light reflector due to its ability to spread light rays over a larger region.
Convex mirrors are used in telescopes to see far off objects clearly in the form of point-sized images.
Another important use of a convex mirror is in the work environment at the time of the production process. A convex mirror placed on conveyor belt assist in viewing a product from varying angles.
