Which characteristic of a sound wave determines its pitch?
Correct Answer: Option D
Explanation:
The pitch of a sound is a subjective sensation that is determined primarily by the frequency of the sound wave. Higher frequency waves are perceived as high-pitched sounds (like a whistle), while lower frequency waves are perceived as low-pitched sounds (like a bass drum). Amplitude determines the loudness of the sound.
