Question

choose the correct answer.
what do scientists call the distance between two crests of a transverse wave?
frequency
wavelength

Explanation:

In the context of waves, frequency refers to the number of wave cycles that pass a given point per unit of time (measured in hertz, Hz). On the other hand, wavelength is a fundamental property of waves (including transverse waves). For a transverse wave (where particle - motion is perpendicular to wave - propagation), the wavelength is specifically defined as the distance between two consecutive crests (or two consecutive troughs). Since the question asks about the “distance between two crests” of a transverse wave, the term that fits this description is wavelength.

Answer:

wavelength
