Nov 23, 2020 - Mirror Formula and Magnification - Light Reflection and Refraction, Class 10, Science | EduRev Notes is made by best teachers of Class 10. 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. If a bus is located at 5.00 m from this mirror, … PLEASE READ MY DISCLOSURE FOR MORE INFO. Answer : In this case, magnification m = 1, since image size = object size (given).

NUMERICALS BASED ON CONVEX AND CONCAVE MIRROR. Please keep a pen and paper ready for rough work but keep your books ... Mirror Formula The relation between the focal length (f), object distance (u) and the image distance (v) is given by 1 f = 1 v + 1 u Magnification . (14.4) where an object OA, is placed in front of a concave mirror. The ratio of the height of the image in a spherical mirror, to the height of the object is called magnification (m). Our aim is to help students learn subjects like (b) Trace the path of … Given below are the links of some of the reference books for class 10 Science. 2. You can use above books for extra knowledge and practicing different questions. Filed Under: Class 10, Light-Reflection and Refraction Tagged With: image distance, magnification, mirror formula, object distance, real image, virtual image About Mrs Shilpi Nagpal Author of this website, Mrs Shilpi Nagpal is MSc (Hons, Chemistry) and BSc (Hons, Chemistry) from Delhi University, B.Ed (I. P. University) and has many years of experience in teaching. In Fig.10.2, distance MN represents the apertur e. We shall consider in our discussion only In addition to the mirror formula, we have the magnification formula What is the magnification formula? The nature of the image will be will be inverted and enlarged, a. Refractive index of an optical medium is ratio speed of the light in air to the speed of the light in the optical medium.So the refractive index of Ruby is 1.71 means ratio of speed of light in air to the speed of light in ruby is equal to 1.71. Thanks for visiting our website. The diameter of the reflecting surface of spherical mirror is called its aperture. All right reserved. Mirror Formulae, Class 10 Science NCERT Solutions. Q 9: Using mirror formula, compute the position of the object placed in front of a concave mirror of focal length f so that the image formed is of same size of the object.

It is also helpful to all the students for competitive examinations. Download free printable assignments and worksheets of class 10 Science. If the object is placed in front of the center of curvature then the image will be formed beyond the centre of curvature.So the image formed is a real image. The surface, then, has a circular outline. There will be total 20 MCQ in this test. To derive concave mirror formula consider fig.
