The distance between two consecutive points in phase on a wave is called the wavelength.

Here's a breakdown:

* In Phase: Two points are in phase if they are at the same point in their oscillation cycle (e.g., both at their maximum positive displacement, or both at their maximum negative displacement).

* Wavelength: The wavelength is the distance between two identical points on a wave, such as two crests, two troughs, or two points with the same phase.
