Final answer:
The greater the frequency of the waves, the higher the sound.
Step-by-step explanation:
The greater the frequency of the waves, the higher the sound. Sound is produced by vibrations that travel through matter in the form of waves. Frequency refers to the number of waves that pass a given point in a certain amount of time, and it is measured in hertz (Hz).
For example, if you compare a small musical instrument like a tambourine to a larger instrument like a drum, the tambourine will produce a higher-pitched sound with a higher frequency. This is because the vibrations of the smaller instrument create waves with a shorter wavelength and higher frequency.
