Formula of light chapter class 10. Knowing light reflection and refraction class 10 questions and answers will help students of class 10 to bag a decent score in class 10 board exams as well. Lets explore problems that appeared in the last ten years of CBSE board exams arranged by subtopic and type of question. At what distance should the object from the lens be placed so that it forms an image at 10 cm from the lens.
CBSE previous question paper problems. Chapter 10 Class 10 Science is mostly about reflection and refraction of light. Its value is 3 10 8 ms -1.
When light rays fall on a surface then most of the rays travel in definite directions from the surface. I Angle of incidence is equal to the angle of reflection. Magnifying power of a concave lens is.
The distances measured in the direction of incident light are taken as positive. The important formulae from the chapter light-reflection and refraction are. Here we have given NCERT Class 10 Science Notes Chapter 10 Light Reflection and Refraction.
