Imagine you’re tuning a guitar and you notice that one string sounds higher-pitched than the others. This string has a higher frequency, which refers to the distance between two wave crests. the speed of a wave. the number of waves that pass a given point in a given time period. the amplitude of a wave.

Understanding Frequency in Sound Waves
Answer:
The correct answer is: the number of waves that pass a given point in a given time period.
What is Frequency?
In physics, frequency is defined as the number of complete wave cycles (or crests) that pass a particular point in a given time interval. It is measured in Hertz (Hz), where 1 Hz = 1 cycle per second.
Frequency and Pitch:
In the context of sound, frequency is closely related to pitch. A higher frequency means the wave oscillates more times per second, which our ears perceive as a higher-pitched sound. That’s why the guitar string that sounds higher-pitched has a higher frequency.
Clarifying the Incorrect Options:
- Wavelength: This refers to the distance between two consecutive wave crests. It is not the same as frequency.
- Wave Speed: This indicates how fast the wave travels through a medium, not how often it oscillates.
- Amplitude: Amplitude is related to the energy or loudness of the sound wave, not its pitch.
