Q: Dependent on the frequency of sound waves, what term described how high or low a sound seems to a listener?


Read this paragraph and choose the correct option from the provided answers:

How high or low a sound seems to a listener is its pitch . Pitch, in turn, depends on the frequency of sound waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time. High-pitched sounds, like the sounds of the piccolo in the Figure below , have high-frequency waves. Low-pitched sounds, like the sounds of the tuba Figure below , have low-frequency waves.
