Question
The amplitude of a sound wave depends upon the _____.
- The force which made the object vibrate
- The energy that it carries
- Both a and b
- None of the above
Hint:
Greater amplitude waves have more energy and greater intensity, so they sound louder.
The correct answer is: Both a and b
- Amplitude is a measure of the size of sound waves.
- The amplitude of the sound wave depends on the force with which an object is made to vibrate.
- Amplitude depends on the amount of energy that started the waves.
- So, the correct option is c.
