NCERT Class 10 Science Chapter 10 Light – Reflection and Refraction PDF Download
Chapter Overview:
This chapter deals with the fundamental optical phenomena of light: reflection and refraction. It begins by explaining the laws of reflection and refraction, highlighting how light behaves when it hits a surface or passes from one transparent medium to another. The chapter provides a detailed study of spherical mirrors (concave and convex), including their image formation properties, principal focus, and focal length. It introduces the widely used mirror formula and the concept of magnification. Furthermore, the chapter explores the refraction of light through spherical lenses (convex and concave), explaining lens formula, power of a lens, and the significance of the refractive index in determining the speed of light in different media.
