Waves and Light

Explore waves through sound, light, and more!

Everything we hear and see is based on information our bodies take in from waves. In this course you’ll learn what waves are, how they travel, and how they interact. Along the way, you’ll apply your knowledge to earthquakes, noise-canceling headphones, ropes, and musical instruments.

By the end, you'll have investigated the nature of light and determined how fast light travels through space. Get ready to gain new perspective as you uncover just how prevalent waves are in everyday life!
