Magnification: The ratio of the height of the image and the height of … • It means they can magnify objects 4 times, 10 times, 40 times, 100 times, and 400 times. Some Important Terms Used In The Reflection Of Light, Some Important Terms Related To Spherical Mirrors, Principal Focus And Focal Length Of A Convex Lens, Principal Focus And Focal Length Of A Concave Lens, Sign Convection For Refraction By Spherical Lenses, Important Questions CBSE Class 10 Science. It is also given in terms of image distance and object distance. This shows that linear magnification produced by a lens is also equal to the ratio of the image distance (v) to the object distance (u). Another way to prevent getting this page in the future is to use Privacy Pass. • Class 10 Physics Light Reflection Refraction: Lens formula & Magnification: Lens formula & Magnification. It is given that in plane mirror, object height and image height are equal. Lens formula is given by: where : u – image distance; v – object distance; f – focal length . 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. It is a pure ratio and has no units. Cloudflare Ray ID: 5f999d191bcf2922 In case of a convex lens, for real and inverted images, the magnification is always –ve and for the virtual and erect image, the magnification is always +ve. It is equal to the ratio of image distance to that of … You may need to download version 2.0 now from the Chrome Web Store. all rights reserved.

Mirror Formula : Where:-The distance of the object from its pole is called the object distance (u). The linear magnification produced by a spherical lens (convex or concave) is defined as the ratio of the height of the image (h′) to the height of the object (h). Light of Class 10 LINEAR MAGNIFICATION PRODUCED BY LENSES The linear magnification produced by a spherical lens (convex or concave) is defined as the … Using magnification formula, prove that image formed by a plane mirror is at the same distance as object but behind the mirror. Formula of Magnification. Performance & security by Cloudflare, Please complete the security check to access. Understanding the magnification physically is quite easy and every one of us can recognize it. It is denoted by the letter ‘m’ and is given by. The distance of the image from the pole of the mirror is called the image distance (v). (ii) For virtual and erect image : According to the New Cartesian Sign Convention, for the virtual and erect images formed by a convex lens. Your IP: 220.127.116.11 Second Formula for Magnification There is another formula of magnification Note : - If magnification (m) is positive , It means image formed is virtual and erect If magnification (m) is negative, It means image formed is real and inverted Questions Example 10.1 - A convex mirror used for rear-view on an automobile has a radius of curvature of 3.00 m. Calculating magnification with the help of lens formula: Magnification of a lens is defined as the ratio of the height of an image to the height of an object. (i) For real and inverted image: According to the New Cartesian Sign Convention, for real and inverted images formed by a convex lens. Class 10 Physics Light Reflection Refraction: Mirror Formula & Magnification: Mirror Formula & Magnification. The linear magnification (m) is also related to the object distance (u) and image distance (v). Moreover, it means that they make an image as large as zoom (appearance).
