Download free printable assignments and worksheets of class 10 Science. (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). To derive concave mirror formula consider fig. Nov 23, 2020 - Mirror Formula and Magnification - Light Reflection and Refraction, Class 10, Science | EduRev Notes is made by best teachers of Class 10. Given below are the links of some of the reference books for class 10 Science. 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. Below you will find the home work assignment for CBSE Class 10 Light- Reflection and Refraction. 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.
