The number of complete waves that pass a given point in a certain amount of time is known as?

Explanation:
The concept being tested is how often a wave repeats over time. That measure is frequency—the number of complete wave cycles that pass a fixed point in a given amount of time. Frequency is expressed in hertz, where one hertz equals one cycle per second. For example, if five complete waves pass a point every second, the frequency is 5 hertz. Wavelength refers to the distance between successive crests, and amplitude is how tall the wave is. Hertz is the unit used for frequency, not the concept itself. The relation v = f λ also ties frequency to speed and wavelength when you know two of the three.
