The chapter Light – Reflection and Refraction in Class 10 Science explains the fundamental properties of light and its behavior when it interacts with different surfaces and mediums. Reflection of light deals with the formation of images using plane mirrors, concave mirrors, and convex mirrors, along with their rules and applications such as in headlights, shaving mirrors, and reflectors. Refraction of light explains how light bends when it passes from one medium to another due to change in speed.
Important concepts like refractive index, lateral displacement, and laws of refraction are covered in detail. Students also learn the working of spherical lenses (concave and convex), image formation, and applications in optical instruments such as microscopes and cameras. This chapter is crucial for board exams as it builds the base for advanced topics in Physics and improves problem-solving skills through ray diagrams and numerical applications.
