Our experts can answer your tough homework and study questions. The magnification of the object for spherical mirrors: Let {eq}h' c. The object is always placed on the left side of the mirror which implies that light falling from the object on the mirror is on the left-hand side. {/eq} and image distance {eq}v The expression which gives t… What is the formula of magnification for mirror? Services, Magnification: Definition, Formula, Calculation & Examples, Working Scholars® Bringing Tuition-Free College to the Community. As a demonstration of the effectiveness of the mirror equation and magnification equation, consider the following example problem and its solution. The pole (p) of the mirror is taken as the origin. The sign convention for spherical mirrors follows a set of rules known as the “New Cartesian Sign Convention”, as mentioned below: a. - Examples & Advantages, Mirrors: Difference Between Plane & Spherical, Light Microscope: Definition, Uses & Parts, Prentice Hall Earth Science: Online Textbook Help, Microbiology for Teachers: Professional Development, CSET Science Subtest I - General Science (215): Practice & Study Guide, DSST Health & Human Development: Study Guide & Test Prep, UExcel Anatomy & Physiology: Study Guide & Test Prep, Introduction to Environmental Science: Help and Review, UExcel Microbiology: Study Guide & Test Prep, Holt Physical Science: Online Textbook Help, Holt McDougal Modern Biology: Online Textbook Help, High School Physical Science: Homework Help Resource, Biological and Biomedical Sciences, Culinary Arts and Personal We can understand in better way using an example. Image distance is the distance of the image from the pole of the mirror and it is denoted by the letter v. And focal length is the distance of the principal focus from the pole of the mirror. e. All the distances … The Mirror formula explains how object distance (u) and image distance (v) are related to the focal length of a spherical mirror. {/eq}. Determine the image distance and the image size. d. All the distances parallel to the principal axis are measured from the pole (p) of the mirror. © copyright 2003-2020 Study.com. b. It is also defined in terms of object distance {eq}u The principal axis is taken as the x-axis of our coordinate system. {/eq} be the height of the image and {eq}h Object distance is the distance of the object from the pole of the mirror; denoted by the letter u. Magnification of the object for plane mirror is one because the height of the image is same as the height of the object. {/eq} that can be expressed as: {eq}\displaystyle m = \frac{h'}{h} = - \frac{v}{u} {/eq}. Example Problem #1 A 4.00-cm tall light bulb is placed a distance of 45.7 cm from a concave mirror having a focal length of 15.2 cm. What is the angular magnification of a lens...
