Convex mirrors are also used in making of magnifying glasses. Convex mirrors are also used for security purposes in various places. The plane mirror is a flat surface, where the object reflected has an image the same size. Convex mirrors are widely used for making magnifying glasses. Not only can they be used to prevent collisions on intersections, they can be mounted as well to protect workers and prevent thievery. Erect - Hence, the image produced to the driver is not inverted, it’s right side is up. All the rays parallel to the principal axis falling on the surface of the convex mirror seem to meet at a point (on the other side of the mirror). Convex mirrors have for long been used to make lenses of sunglasses. They increase the amount of light; this makes it easier to light up streets with low energy usage. the image provided by a convex mirror is. Therefore, the most common convex mirror uses are in places where bigger objects are to be viewed in a smaller size. A convex mirror has the ability to spread light across a large surface area. Street Light Reflectors. In order to make a magnifying glass, two convex mirrors are placed back to back. This article was written by the It Still Works team, copy edited and fact checked through a multi-point auditing system, in efforts to ensure our readers only receive the best information. The concave mirrors, curved as the inside of a bowl, are used for focusing light, and the images often appear larger and upside down to the original object. Convex mirrors have many applications. They are places near ATM’s so that bank customers can check if someone is behind them. Convex mirrors are often used on vehicular rear-view mirrors. Security personnel (and security cameras) can watch the mirrors, and the mirrors can be coated so that cameras can be mounted inside. We will need huge plane mirrors to cover the width seen through a convex mirror of much smaller size. In order to make a magnifying glass, two convex mirrors are placed back to back. It is cut out from a glass sphere, and its one surface is painted.

Stay tuned with BYJU’S to learn more interesting Physics concepts with the help of interactive video lessons. Therefore, it covers are a larger field of view compared to a plane or concave mirror. Pro Lite, Vedantu They can be made of metals or polycarbonates, and can have varying degrees of curvature. (image will be uploaded soon) They are used in street lights as they are good reflectors of light. In automated teller machines, there is a convex mirror present close to the top of the machine. Hence everything appears smaller, and it covers a wider view. It is a spherical mirror curve outward. Convex mirrors are useful for inspecting places difficult to get to. A convex mirror is a spherical reflecting surface in which its bulging side faces the light source. The distance between the pole and the focus is known as the focal length. They can also be mounted in corners, where two passages come together. They can be obvious, or not noticeable, but it would be difficult in some situations to be without them. This is so that one can see what is behind their back. This means that when a parallel light ray hits a convex mirror, it reflects outwards and travel directly away from an imaginary focal point. Convex mirrors are also used in security situations. There are also convex mirrors specifically meant for use on forklifts, again for avoiding collision situations in a warehouse environment. To submit your questions or ideas, or to simply learn more about It Still Works, contact us. This is primarily because of their ability to magnify lenses. It has an imaginary Focal Point (F) and the Centre of Curvature (2F) which cannot be reached hence, the mirror forms a virtual image. Your email address will not be published. In a reflector telescope, light from the object of interest enters the far end of the telescope and strikes a concave mirror at the end close… Since convex mirrors have a wider view field than concave mirrors and plane mirrors, they are mostly used inside mirrors of automobiles. Mirrors are surfaces that reflect light creating images of objects in front of them. The point is known as the focus or focal point. Convex mirrors are widely used for making magnifying glasses. Pro Lite, Vedantu Compared to other reflective mirrors, the field of view for a convex mirror is the maximum. Convex mirrors are also used in security situations. The convex mirror always forms a virtual image of the object and the image formed by the convex mirror is smaller than the size of the actual object. 4. Convex mirrors are used outdoors, similar to indoors, to avoid collisions. They are used in driveways, roads, and alleys to provide safety to all the bikers and motorists at curves and turns and other places where there is … Mirrors can be mounted near corners on the walls, or over intersections on the ceiling. Convex mirrors are often used in the hallways of buildings including stores, schools, hospitals, hotels and apartment buildings. Two convex mirrors are placed back to back to create the magnified effect. The bulged out surface reflects the light outwards and are not used to focus the light. A convex mirror has a wider range of view than a plane mirror, giving it many uses, especially relating to safety. Uses of the convex mirror in a magnifying glass. The convex mirror is used as side-view mirror on the passenger’s side of a car because it forms an erect and smaller image for the way behind the car. This is because the rays of light falling parallel once reflected diverge. Uses of the convex mirror. In hallways, they are put at intersections or at blind spots in the corridors to improve the visibility for people walking there. The center of the glass spheres the mirror has been cut from is called the center of curvature. These were some of the common convex mirrors uses in the practical world. Uses of Convex Mirror. They give a larger view when compared to plane mirrors. The radius of curvature is double the focal length. Thank you Byjus. Convex Mirrors and Vehicles The convex mirror is curved as the outside of a bowl, reflects a wider viewing area and the images reflected appear smaller. Some of the most vital and common uses of convex mirror is described below. Convex mirrors can be found indoors and out, on vehicles and in conjunction with security cameras. Sorry!, This page is not available for now to bookmark. This is because all the rays falling on its surface seem to be diverging from one point being the focus. You can see if anyone is looking while you are entering your pin. Some convex mirror uses are listed in the points below. A convex mirror is used as a rear-view mirror because. Instead of having more than one security personnel we can use multiple convex mirrors on the ceiling. The information is really helpful for 8th and 9th standards. Today, two types of telescopes are widely used: refractor telescopes, which employ lenses, and reflector telescopes, which have mirrors.

Convex mirrors are also used for security purposes in various places. Vedantu academic counsellor will be calling you shortly for your Online Counselling session. The mirrors are mounted on rods of the appropriate size, and can be extended with lights under objects to view the underside.
