Which term describes the distance from one point on a wave to the same point on the next wave? crest frequency trough wavelength

Wavelength

the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats. It is thus the inverse of the spatial frequency. Wavelength is usually determined by considering the distance between consecutive corresponding points of the same phase, such as crests, troughs, or zero crossings and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns.

The correct answer is: Wavelength

Explanation:
Wavelength of a wave is defined as the distance between a point on one wave and the same point on the next wave. The easiest way to find the wavelength of the wave is by choosing the Crest of one wave and find the distance of that point to the Crest of the next wave. Hence, the right answer is "wavelength."
