Waves & Sound

How does energy travel through a medium? This section explores the mechanics of wave motion, from ripples on a pond to the complex harmonics of musical instruments and the Doppler effect.

A digital sound wave shown on a computer screen against a dark background. — Sound travels in waves. This picture shows a sound wave on a screen. The tall parts show where the sound is loud, and the patterns show how fast the air is vibrating to make the noise you hear.
