- Plate
- Hands
- Air
- None of the above
Hint:
When an object is hit by another, the vibrations produce sound.
The correct answer is: Plate
This is due to the vibration of the plate.
- The sound is produced when an object is hit by another.
- So when a steel plate is hit by a spoon it creates frequencies of a high pitch which creates a grave sound.
- In return, the spoon vibrates the plate and thus produces sound.
- Thus, the sound is due to the vibration made on the plate.
