Question:

Explain how sound is produced N by your school bell.

Answer:

The bell of our school is made of alloy which vibrates by striking the hammer. Vibration causes disturbance in the air. A wave is a disturbance that vibrates and forth in the air and reaches our ears. The particles of the medium simply oscillate and the disturbance proceeds.
