Question
We are able to hear sound originating from various objects as ____.
- The medium in which we are located is a material medium
- The sound is able to propagate through the medium
- The particles of the medium vibrate to transmit sound.
- All of the above
Hint:
Sound is a mechanical wave.
The correct answer is: All of the above
- Sound is produced when an object vibrates, creating a pressure wave, and transmitting.
- Sound is a mechanical wave, they need a material medium for propagation.
- So, the correct option is d.
