CBSE Class 7 Science Chapter 15 Light MCQ Questions with Answers

# CBSE Class 7 Science Chapter 15 Light MCQ Questions with Answers

This chapter is all about understanding light, which is a vital part of our everyday lives. Light is a form of energy that allows us to see everything around us. It travels very fast and in straight lines. By learning about light, we can better understand how we see things and how light behaves in different situations.

In this chapter, you will learn about how light can reflect off surfaces, like when you see yourself in a mirror. You’ll also discover how light can bend when it passes through objects like water or glass, a process called refraction. Additionally, we will explore how white light can split into different colors, a phenomenon known as dispersion. These concepts are not only interesting but also help us understand many natural and technological processes.
