Question
The picture below shows three sound wave forms. They have the same ____.
- Pitch
- Loudness
- Quality
- All of the above
Hint:
Pitch is the same in the frequency of the wave
The correct answer is: Pitch
- The total number of waves produced in one second is called the frequency of the sound wave.
- Sounds are higher or lower in pitch according to the frequency of vibration of the sound waves producing them.
- The amplitude of a sound wave can be defined as the loudness or the amount of maximum displacement of vibrating particles of the medium from their mean position when the sound is produced.
- Therefore, the pitch is the same for all waves but the amplitude is different.
