Question

which of the following properties of a sound wave is most closely associated with the pitch of the sound?
a. the amplitude
b. the wavelength
c. the wave speed
d. the frequency

Explanation:

The pitch of a sound is determined by its frequency. Higher - frequency sounds have a higher pitch, and lower - frequency sounds have a lower pitch. Amplitude is related to loudness, wavelength and wave speed are related to the physical characteristics of the wave medium and propagation but not directly to pitch.

Answer:

D. The frequency
