The pitch of a sound wave depends upon which one of its following characteristics?
Frequency
Concept:
- Pitch tells us about the frequency of sound, which means the highness or lowness of sound.
Explanation:
From the above diagram, we can see that the higher the frequency, the higher the pitch will be, and the lower the frequency, the lower the pitch will be.
Additional Information
- Sound waves are longitudinal waves.
- Intensity determines the strength of the sound wave at a location or how strong the sound wave is.
- It directly depends on the amplitude of the sound waves and increases with the amplitude of the sound wave.
- Since amplitude is related to intensity, the intensity of sound is given by the following formula,
- L 2 - L 1 =10log 10 ( \( {I \over Io}\) ) ; where I is the intensity of sound at a point and I o = 1× 1012 Wm-2 .
- Intensity is a relative term, so we have taken the difference.
