A sound wave with a low frequency will have _______.
-
A.
a low amplitude
-
B.
a short wavelength
-
C.
a high pitch
-
D.
a low pitch
Correct Answer:
D. a low pitch
Explanation:
The correct answer is a low pitch.
The pitch of a sound is directly determined by its frequency. Frequency refers to the number of vibrations or cycles a sound wave completes in one second. When a sound wave has a low frequency, it means the vibrations are occurring relatively slowly, which the human ear perceives as a deeper or lower pitch. In contrast, high-frequency waves create a high-pitched sound. Amplitude, on the other hand, relates to the loudness of the sound rather than its tone, and wavelength is inversely proportional to frequency, meaning a low-frequency sound would actually have a long wavelength. Therefore, a sound wave with low frequency is characterized by a low pitch.
