CBSE Notes Class 8 Science Chapter 10 Light: Mirrors and Lenses

Light is the medium through which we perceive the world, and its behavior changes when it hits different surfaces. This chapter focuses on Reflection and Refraction. Also study Spherical Mirrors: Concave mirrors (which converge light to a point and are used in torches) and Convex mirrors (which provide a wide field of view, used in vehicle side-mirrors). Furthermore, the chapter introduces Lenses, which work by bending light as it passes through.

By understanding the focal length and image formation, we can explain how the human eye works and how we have built tools like microscopes and telescopes to see the invisible and the distant. Students learn about types of mirrors and lenses and image formation. This CBSE Class 8 Science chapter builds a strong base in optics.
