A sound wave with a low frequency will have _______.
-
A.
a low amplitude
-
B.
a low pitch
-
C.
a high pitch
-
D.
a short wavelength
Correct Answer:
B. a low pitch
Explanation:
The pitch of a sound is directly determined by its frequency. Frequency refers to the number of vibrations or cycles per second; therefore, a sound wave with a low frequency vibrates slowly and produces a sound that is perceived as low in pitch. In contrast, high-frequency waves create high-pitched sounds. Characteristics like amplitude relate to volume, while wavelength is inversely proportional to frequency, meaning a low-frequency wave would actually have a long wavelength rather than a short one.
