The distance between one point on a compression and the corresponding next in a sound wave is called a wavelength.

Here's why:

* Compression: A compression is a region of high pressure in a sound wave.

* Wavelength: The wavelength is the distance between two consecutive points in a wave that are in the same phase, such as two compressions or two rarefactions.

Therefore, the distance between one compression and the next is one complete cycle of the wave, which is its wavelength.
