To understand how this happens, consider Figure \(\PageIndex{1}\). For An Inverted Image, Which Relationship Always Holds True? O The Magnitude Of Y Equals The Magnitude Of Y. This document is highly rated by Class 12 students and has been viewed 4818 times. Lateral magnification: Lateral magnification is one way you can describe how big the image is compared to the original object. The Lateral Magnification M For A Mirror Is Calculated With The Equation M, In Which Y' Is (1 Poin The Image Height And Y Is The Object Height. for the magnification factor, the equation will also deal with inversion. Here are the equations: Locating images formed by mirrors: An object placed a certain distance away from a mirror will produce an image at a certain distance from the mirror. For a plane mirror, we showed that the image formed has the same height and orientation as the object, and it is located at the same distance behind the mirror as the object is in front of the mirror. Nov 24, 2020 - Types of Mirrors, Mirror Formula and Magnification Class 12 Notes | EduRev is made by best teachers of Class 12. 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. OThe Signs Of Y And Y' Are The Same. Images in a plane mirror are the same size as the object, are located behind the mirror, and are oriented in the same direction as the object (i.e., “upright”). The Signs Of Y And Y' Are Opposite. The magnification factor is exactly the ratio of the height of the image to the height of the source; the similar triangles give this ratio as h'/h = i/s, which can be found using the position formula. Answer to The lateral magnification of a plane mirror is (a) greater than 1, (b) less than 1, (c) equal to +1, (d) equal to −1.. Two rays emerge from point \(P\), strike the mirror, and reflect into the observer’s eye. Mirror Formula and Magnification Posted on 21/11/2019 21/11/2019 by myrank Mirror formula gives the relationship between image distance, object distance and the focal length of the mirror and this formula is valid in all situations for all spherical mirrors for all positions of the object. In some cases where the mirrors are curved, you may be given the focal length of a mirror. In fact, using the sign conventions mentioned above, if we use. M = -i/s. Here (1/u)+(1/v)=1=(1/f) And (1/u')+(1/v')=(1/f) for the very two positioning of the ends of the object longitudinally as u and u' respectively with their image position as v and v' respectively.
