Question

the number of complete wave cycles that pass a given point in a specified amount of time (usually one second).
wavelength
frequency
amplitude

Explanation:

• Wavelength: It is the distance between two consecutive crests or troughs of a wave.
• Frequency: It is defined as the number of complete wave cycles that pass a given point in a specified amount of time (usually one second).
• Amplitude: It is the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.

Answer:

Frequency
