At our homes, we have a plane mirror where the image of the reflected object is the same as the size of the object itself. In a concave mirror, the reflected image is enlarged. A concave mirror can also present an inverted image if the object is kept far away from the mirror. Whereas the convex mirror will always produce a virtual, erect and highly diminished in size image. Thus you can recognize the mirror from the characteristics of the image that is produced.
The study of mirrors is one of the fundamental topics in physics. Do you see how closely this science is connected to our daily lives? Each morning and evening we see our reflection in the mirror at home - we tend to see not only the external self but also end up reflecting on what is going on inside of us. It is said smiling to yourself in the mirror, first thing in the morning fills your day with positivity!

No two agencies are the same. Whatever you need from a police body camera - live streaming, holster triggers, rapid checkout - our body cameras are up for the task.
Also, due to the above property the size of the object’s image is smaller as compared to the actual object’s size. Therefore, a convex mirror is the most appropriate in those areas where large objects have to be viewed in a tiny size. This makes it easy for a person to view the image.
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.
A convex mirror is also commonly called a curved mirror. Where the reflective surface of a concave mirror bulges towards the inward direction, in the case of a convex mirror it bulges in the direction where the light source is located.

In a convex mirror, all the light rays converge as a focused beam to meet at the focal point. The focal length is the distance between the focal point and the front of the convex mirror. Why does the convex mirror bend outward toward the source of light and form an imaginary image? This is because the center of curvature and focal point are both imaginary. They cannot be reached or measured completely. Hence the image produced by this mirror is an upright, virtual one that cannot be projected onto a screen. When the object being reflected lies at infinity, then a tiny, erect, diminished and virtual image is produced at the principal focus point which lies behind the mirror. When the object lies between the pole and the infinity of the convex mirror, then the diminished image produced lies between the pole and focal point behind the mirror.
When the object lies at infinity, then a tiny image is produced at a principal focus point. This point is located behind the mirror. You will see that the image produced is virtual, highly diminished and erect.

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.
Because a convex mirror has a broader reflective area as compared to other mirrors, one of its most important applications is that it is used to provide a good overview of the rear and side view of the roads. This helps the drivers of cars and automobiles foresee risks and avoid unwanted accidents.
The image of the object formed by a concave mirror is bigger than the actual size of the object. In the case of a convex mirror, it makes the object appear smaller in size. A concave mirror is used to magnify the image of the object but a convex mirror reduces the image size so that it gets accommodated easily in the mirror.

A convex mirror has broader fields of view as compared to reflective surfaces of concave and plane mirrors. Due to this, convex mirrors are used in forming side mirrors off an automobile. These mirrors provide a fish-eye view to the person who drives the automobile. This feature helps them to get a clear view of the rear area of the road easily.
The convex mirror is also known as a curved, diverging or fish-eyed mirror because the reflective surface bulges outward in the direction of the light rays. As a result, the focal point and center of curvature are located behind the mirror which means they are imaginary and unreachable. The object’s image that is produced is essentially smaller in size, virtual and erect.

A convex mirror is given the name of a "diverging mirror". It is because of the behavior of the mirror that makes light rays 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.
Stay connected through your shift with the V700 body camera. With LTE and built in connections with Motorola Solutions products you can be confident that the body camera can be livestreamed and capture important evidence.
Apart from this, it is used in street lights because it can scatter light rays over a wider region and in telescopes to see far-off objects like stars as tiny objects.
The virtual image created of the object has a smaller size than its actual size. It provides a wide field view. Convex mirrors provide heightened safety for motor drivers on roads, alleys, and driveways where very little visibility is there.
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.

You will see an inverted form of the image when the object is kept at a far distance from the mirror. It is only a concave mirror that has the ability to generate an actual inverted image. The size of the image produced by a concave mirror is based on the screen placement. In the case of a convex mirror, it always generates a small-sized straight image.

Automobiles: 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. The convex mirror is one of the important things that offer a clearer rear view of the road to ensure maximum safety all the time.
Convex mirrors are also popularly called the fish eye mirror or diverging mirror. Its reflective surface bulges in the direction of the light source. A convex mirror has the ability to reflect all the light that falls on them in the outward direction. So, the type of image formed by these mirrors is always imaginary/virtual.
Where a convex mirror bulges outward towards the source of light, the reflective surface of the concave mirror curves inward. The image formed on a convex mirror is smaller than the actual size of the object while the image in a concave mirror is larger than the actual object size. A concave mirror is used when we wish to magnify the reflected image while with a convex mirror the size is reduced so that it is accommodated in the mirror.
It implies that the type of image made by this type of mirror can’t be projected on the screen. The image generated by the convex mirror is an upright virtual image that is relatively smaller in size than the size of the projected object.

When an object lies between the pole and infinity of this mirror, then you will see a diminished form of an erect and virtual image. This image is created between focus and pole behind the convex mirror.

Convex mirrors are kept close to the ATM or automated teller machine to permit the customers to figure out whether someone is standing behind them. 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.
Intuitive to operate, easy to integrate with existing architecture and workflows, equipped with all of the crucial features you need for a body camera - the VB400 body camera is the budget-friendly choice for small to mid-size agencies.
Another important use of a convex mirror is in the work environment at the time of the production process. A convex mirror placed on the conveyor belt assists in viewing a product from varying angles.
Large hospitals, hotels, 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.
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.

When you use a plane mirror, you will find that the size of the image generated by it will be the same as the actual size of the image. In the case of a concave lens, you will find that when the object is placed near the mirror, its image gets enlarged.
Now let us understand the type of image formed by a convex mirror. A curved or convex mirror bends outward in the shape of a dome. It always forms an imaginary image. The reason behind it is that the “center of curvature” and the point of focus are both imaginary points in the mirror. Both of these points are unable to be reached.
Convex mirrors are kept beside ATMs to tell the customer if someone is standing behind him. This is to ensure security while using the ATM, prevent theft of cash withdrawals and secure the identity of the user.
