What affects pitch?

What affects pitch?

• A. The amplitude of the wave
• B. The frequency of the sound wave
• C. The speed of sound in the medium
• D. The duration of the note

Answer: (B)

Pitch is determined by how often the sound wave repeats each second. The frequency, counted in hertz, is the number of cycles per second; higher frequency means more cycles per second and a higher pitch, while lower frequency gives a lower pitch. The amplitude of the wave changes how loud the sound is, not how high or low it sounds. The duration of the note only affects how long the tone lasts. The speed of sound in a medium affects how fast the wave travels and its wavelength, but for a given frequency the perceived pitch stays the same, so it doesn’t change the note’s pitch itself.
