C) is remaining constant.
D) cannot be determined.

Question

Quizplus · Accepted Answer

The pitch of a sound is directly related to its frequency. As the pitch increases, the frequency of the sound waves increases. Since the speed of sound in a given medium is constant, an increase in frequency results in a decrease in wavelength. Therefore, if the pitch of the sound is increasing, the wavelength is decreasing.

If the Pitch of the Sound Is Increasing, Then the Wavelength
