The answer is 'wavelength'.
The term for the distance between two crests of a water wave is called the wavelength. It is measured as the distance from one peak of the wave to the next peak.
The distance between one complete wave is called the wavelength. It is measured as the distance between two consecutive points that are in phase with each other, such as from one peak to the next peak or one trough to the next trough.

That is called its' wavelength. From a selected point to the next similar point. Peak to peak for example.
The distance between one point on a wave to the same point on the next wave is called the wavelength. It is a measure of the distance covered by a complete cycle of the wave, such as from peak to peak or trough to trough. The wavelength is inversely related to the frequency of the wave.
The distance between two adjacent compressions or rarefactions is called the wavelength. It is measured as the distance from one point on a wave to the corresponding point on the next cycle, either peak to peak or trough to trough.
Wavelength is the distance between the crests in waves. It is also the distance between one peak of a wave to the next corresponding peak.
Wavelength
In a wave, the distance from peak to peak is called the wavelength. It is the physical distance between two similar points in the wave's cycle, such as two consecutive peaks or troughs.
the distance between one peak to the next
If you mean between two positive, or two negative, peaks of an electrical wave, it's the wavelength. If it's a pressure wave, "peak" is usually taken to mean "maximum pressure", so it would be between "peaks".
The vertical distance between a wave's midpoint and its crest or trough is called is peak amplitude. This differentiates this measurement from the vertical distance from a crest to a trough, which is called its peak-to-peak amplitude.
