When a steel plate is hit by a steel spoon, a sound is produced. This is due to the vibration of the ____.

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.
