* Short wavelength: Waves with short wavelengths are squished together, meaning the distance between two peaks (or troughs) is small. Think of a tightly coiled spring.
* Long wavelength: Waves with long wavelengths are spread out, with a larger distance between peaks (or troughs). Think of a loosely coiled spring.
Wavelength is a key characteristic of waves, and it's related to other wave properties like frequency and energy.
