What Does Wavelength Mean?
- A wave is a two-dimensional, repetitious arch, and a wavelength is the measure of the distance between each repeated highpoint.

With varying degrees of technicality, it's possible to measure the wavelengths of waves made up of light, sound or physical matter (in the form of a liquid). - The easiest way to visualize a wavelength is to imagine the measure of the length of each ripple, from one crest to the next, in calm water.

There are infinite sizes of wavelengths, from microscopic to colossal. In visible light waves, different wavelengths create different colors, and in audible sound waves, different tones. - In a water wave, the wavelength doesn't represent how far each particle travels. Instead, the water particles move in an up-and-down motion as waves pass by.
