# Ch 8: Waves, Sound, and Light

Watch online natural science video lessons and take the quick quizzes to measure your understanding. Learn about the different aspects of waves, sound and light.

## Waves, Sound and Light - Lessons and Learning Objectives

Light and sound are a part of our everyday lives. We rely on them in many ways to keep us safe, alert us and entertain us. Do you know how they work, though? Are you aware of the different types of sound and light waves? If you are not quite sure about the answers to those questions, then this chapter is for you. These lessons will discuss the ideas of vibrations and waves. You'll learn about how different wavelengths produce different types of sound and light. Some of the other things you will learn include:

• The definition of sound
• The categories in the electromagnetic spectrum
• Color in light
• Snell's law
• The Doppler effect
• Wave-particle duality
