Solution Light Reflection And Refraction Class 10 Notes St The speed of light in vacuum is 3 x 108 ms 1. answer . refractive index of a medium (nm) = speed of light in vacuum speed of light in the medium. speed of light in vacuum (c) = 3 × 10 8 m s. refractive index of glass (ng) = 1.50. speed of light in the glass (v) = speed of light in vacuum refractive index of glass. Question 1. find the focal length of a convex mirror whose radius of curvature is 32 cm. solution: r = 32 cm and f=\frac { r } { 2 } = \frac { 32 } { 2 } = 16cm. question 2. a concave mirror produces three times magnified (enlarged) real image of an object placed at 10 cm in front of it.
Solution Class 10 Science Chapter 10 Light Reflection And Ref Direct the light reflected by the mirror onto a sheet of paper held close to the mirror. move the sheet back and forth slowly until a bright, sharp spot of light is seen on the paper. the distance of this image from the position of the mirror gives the approximate value of the focal length of the mirror. 2. Cbse class 10 science notes chapter 10 light reflection and refraction. reflection. reflection of light: the phenomenon of bouncing back of light into the same medium by the smooth surface is called reflection. incident light: light which falls on the surface is called incident light. reflected light: light which goes back after reflection is. The phenomenon of reflection and refraction of light explained in science chapter 10, light reflection and refraction is based on the manipulation of straight traveling light waves due to the presence of objects. the reflection of light is seen due to the presence of a shiny reflecting surface on which light falls and bounces back, maintaining. This free pdf contains solutions to all problems in light reflection and refraction class 10. class 10 science chapter 9 is mostly about the reflection and refraction of light. the main topics included spherical mirrors, magnification, reflection, refraction, and lens power. light reflection and refraction class 10 solutions include diagrams.
