📖 Lesson Introduction

Waves have different properties that help describe how they move. Amplitude is the height of a wave and shows how strong or powerful the wave is. Wavelength is the distance between two matching parts of a wave, such as crest to crest. Bigger amplitudes mean stronger waves, while longer wavelengths mean the waves are spread farther apart.
