In most of the measuring instruments, a plane mirror is placed under the scale and pointer. A ray of light falling on a plane mirror is reflected at the same angle as the angle of incidence. A luminous body is a source of light. Also, we already know that plane mirrors are primarily used to see the reflection of an object. Ans. State 5 uses of plane mirror 2 See answers vaddarahallicircle6 is waiting for your help. Applications and Uses of Mirrors Periscopes and kaleidoscopes Automobiles Torch Lights Shaving Mirrors In Dentist Solar Cooker Security The real image is always inverted and can be produced with a converging (convex) lens and a concave mirror.Â. Without any doubt, the solar cooker is the most effective and efficient way of utilizing the renewable source of energy for cooking-related purposes.Â, Plane Mirrors - Used for Safety and Security, Plane mirrors are widely used for finding the explosives underneath the vehicles. • They are used to make kaleidoscope. Sign up for the amazing classes of A level physics tuition, O level physics tuition, JC physics tuition in Singapore. 2. Reproduction in whole or in part without permission is prohibited. Two parallel plane mirrors can form an infinite number of images. A virtual image is produced when the light rays from a source donât cross or meet at a point to form an image. Plane mirrors have many uses apart from the obvious one of simply to look in. When a light ray falls on a surface, then it can undergo one of the three phenomena, namely, reflection, refraction, and absorption. There are two laws of reflection that are applicable to a plane mirror. Why? What are the uses of (i) plane mirror, (ii) concave mirror, (iii) convex mirror? • Performance & security by Cloudflare, Please complete the security check to access. Ordinary plane mirrors are coated at the back so that the incident ray is reflected from the back surface instead of the front surface. We hope you have understood the uses and properties of a plane mirror. Since they both are inclined at 45 degrees to the incident light and therefore reflect the light twice such that the incident rays and reflected rays in both cases are perpendicular. A non-luminous body does not emit any light of its own and therefore becomes visible only after our eye perceives incident light reflected from another source. refraction through lenses and optical instruments. Define the Principal focus of a (i) Convex lens and (ii) Concave lens. A plane mirror has various exclusive features and characteristics corresponding to the image that it forms, which are as follows: A plane mirror always forms a virtual image. Why are ordinary plane mirrors coated on the back? Ans. The distance of the object from the mirror (object distance. The front surface can be damaged easily due to scratches and watermarks. Can a plane mirror form multiple images? Hence, we can conclude by saying that a real image is captured on the screen, and it appears to be on the same side as the object. © 2020 (Science Facts). define yhen with example , meet.google.com/ywz-htrj-wwphot girls join fast for fun.......only girls who will on cam and show. A plane mirror is a mirror that has a flat reflecting surface without any inward or outward curve. If two or more plane mirrors are placed at a certain angle, then multiple images can be formed. When it falls on a normal surface than most of the light gets absorbed. This makes the objects above the sea visible to people moving in submarines below it. 2. You may need to download version 2.0 now from the Chrome Web Store. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. The virtual image is always erect and can be produced with a diverging (concave) lens, a convex mirror, and a plane mirror. Miracle Learning Centre would like to bring you more articles on Physics tuition concepts. (ii) Uses of concave mirrors mohammedimad2815 mohammedimad2815 Answer: please follow me please. Plane mirrors are used in dressing tables to see ourselves. On the other hand, a virtual image can never be captured or obtained on a screen, and it appears to be on the opposite side as that of the mirror. State two applications each of (i) convex lens, and (ii) concave lens. When the pointer moves, the image in the plane mirror also moves. For forming an image with the help of a plane mirror, we require at least two rays of light from an object that either meet or appear to meet at a point. The image formed or produced by a plane mirror is always of the same size as that of the object. The plane mirrors used in periscopes in submarines reflect the images of all the ships that are present on the surface of the water. Plane mirrors are used as looking glass. It emits light on its own. All rights reserved. Cloudflare Ray ID: 5f1779a43cdd1e5d Ex: chair, umbrella, hair. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Example: A black cloth. • The image is of the same size as that of the object, i.e., magnification = 1. The image is laterally inverted, i.e., if the left hand is raised, it appears, as though the right hand has been raised on the image. As the real image is a result of the actual intersection of a light ray, it can be captured on screen. 2. This image is not real but virtual because the image formed behind the mirror by extending the diverging reflected rays backward. As a result, the image formed by the mirror is sharp and undistorted. This phenomenon is known as lateral inversion. If their densities are in the ratio 3:2, theratio of th Add your answer and earn points. Types of Blood Cells With Their Structure, and Functions, The Main Parts of a Plant With Their Functions, Parts of a Flower With Their Structure and Functions, Parts of a Leaf With Their Structure and Functions, Has an infinite focal length and radius of curvature, Has a finite focal length and radius of curvature. Use of plane mirrors: 1. The focal length of a plane mirror is infinity. Required fields are marked *. Most of the light gets absorbed when a ray of light falls on a normal surface. …, define physical quantity. Find the forcerequired to stop the same body in same timewhen it is moving wit For a plane mirror, angles of incidence and reflection are equal. They are also used in constructing periscope which is used in submarines. Plane mirrors are placed on the inside walls of the shops like jewelry shops. how many types of physical quantities are there? 3. They are used in periscopes, for signalling, in kaleidoscopes, to see round dangerous bends, in meters, as mirror tiles, in a sextant, in an overhead projector, an SLR camera, car wing mirrors, in microscopes and as reflecting number plates to mention only some! A plane mirror always produces the images that have a magnification of '1.' A plane mirror has several different uses and applications, including periscopes and kaleidoscopes, automobiles, shaving mirrors, dentists' mirror, torch lights, solar cookers, and security-related purposes. In most of the measuring instruments, a plane mirror is placed under... 3. A horizontal parallel beam of light passes through a vertical convex lens of focal length 20 cm and is then reflected by a tilted plane mirror so that it converges to a point I. what are the uses of concave and convex mirrors? Example: A light blue cloth. They are used in periscopes, for signalling, in kaleidoscopes, to see round dangerous bends, in meters, as mirror tiles, in a sextant, in an overhead projector, an SLR camera, car wing mirrors, in microscopes and as reflecting number plates to mention only some! The plane mirrors are also exclusively used in microscopes to reflect the image of the object that is being monitored.Â, Plane mirrors are used in solar cookers as they are capable of reflecting most of the sunlight or sun rays that fall on their surface. Without the mirrors, it would have been extremely difficult for us to manage such things. How will you distinguish between a plane mirror a concave mirror and a convex mirror without touching them? The plane mirrors and colour glass used in kaleidoscopes reflect many colourful patterns.Â, For reflecting powerful beams of parallel light, vehicles widely used mirrors in their headlights. USES OF PLANE MIRROR ARE - 1. Uses of the concave mirror. A good emitter reflects most of the incident light falling on it. Therefore, we can say that mirrors are polished surfaces, which are coated with Mercury (chemical symbol Hg) so that they can reflect most of the light that falls upon them.Â We can classify mirrors as a convex mirror, concave mirror, or a plane mirror, based on the reflecting surface. Example: a silvery surface. Plane mirrors are used as looking glass. Kaleidoscopes are interesting, they are made with two mirrors at an angle to each other.
