All material given in this website is a property of and is for your personal and non-commercial use only, $Magnification = \frac {h_i}{h_o}=-\frac {v}{u}$, If the object is placed at 25 cm in front of the concave mirror having focal length 20 cm, this means that the object is placed in between focus and the centre of curvature of the mirror. 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. It is also known as a mirror formula. Mirror Formulae, Class 10 Science NCERT Solutions. © 2007-2019 . CLASS – X 2014 – 15 CHAPTER WISE CONCEPTS, FORMULAS AND NUMERICALS INLCUDING HOTS PROBLEMS Prepared by ... All concepts and formulas based on Numerical and HOTS Numerical are also included in the material. In a spherical mirror: The distance between the object and the pole of the mirror is called the … Figure 10.2 (a) Concave mirror (b) Convex mirror (b) (a) Light – Reflection and Refraction 163 The reflecting surface of a spherical mirror is by-and-large spherical. 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, find the position, nature and size of the image View Answer Example 10.2 – An object, 4.0 cm in size, is placed at 25.0 cm in front of a concave mirror of focal length 15.0 cm. There will be total 20 MCQ in this test. Thanks for visiting our website. For any content/service related issues please contact on this number . ... An object 4 cm in … ... (ii) The incident ray, the normal to the mirror at the point of incidence and the reflected ray, all lie in the same … The ratio of the height of the image in a spherical mirror, to the height of the object is called magnification (m). (a) Write two rules of the new Cartesian sign conventions for spherical mirrors. Lakhmir Singh, Together with CBSE/NCERT Practice Material Chapterwise for Class 10 Science, Mastering Numericals and Objectives of Physics for Class X. 8788563422. Answer : In this case, magnification m = 1, since image size = object size (given). The answer is convex mirror as its forms an erect diminished virtual image for all the positions of the object placed in front of it.

Free PDF Download- Best collection of notes, important questions , sample papers and NCERT Solution for CBSE Class 10 Science. 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. Concave mirror formula. A ray of light starting from the end point A of the object and moving parallel to the principal axis strikes the mirror at the point E. it is reflected at E and passes through the principal focus F. 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, … Given below are the links of some of the reference books for class 10 Science.
