Question

On which property of vibrations determines the pitch of the sound? Explain with examples.

Answer 1

1. The frequency determines the shrillness or pitch of sound. 

2. If the frequency of vibration is higher we say that the sound has a higher pitch. 

3. If the frequency of vibration is lower, we say that the sound has a lower pitch. For example, the drum vibrates with a low frequency. Therefore, it produces a low pitched sound: 

4. On the other hand, a wristle has a higher frequency, and therefore produces a sound of higher pitch. 

5. A bird makes a high pitched sound whereas a lion makes a low pitch roar.
