The pitch of a sound primarily depends on the frequency of the sound wave, not its amplitude.
Frequency refers to the number of cycles or vibrations of a sound wave that occur per unit of time. It is measured in Hertz (Hz) and determines the perceived pitch of a sound. Higher frequencies are associated with higher pitches, while lower frequencies are associated with lower pitches. For example, a high-pitched sound like a whistle has a higher frequency than a low-pitched sound like a bass drum.
On the other hand, the amplitude of a sound wave refers to the magnitude or strength of the wave. It represents the amount of energy carried by the sound wave and is related to the perceived loudness or volume of the sound. Greater amplitudes generally correspond to louder sounds, while smaller amplitudes correspond to softer sounds.
While the amplitude of a sound wave can influence our perception of loudness, it does not directly affect the pitch. In other words, changing the amplitude of a sound wave while keeping the frequency constant would alter the loudness of the sound but not its pitch.
