Explain how sound is produced by your school bell.

उत्तर
When the school bell vibrates, it forces the adjacent particles in the air to vibrate. This disturbance gives rise to a wave, and when the bell moves forward, it pushes the air in front of it. This creates a region of high pressure known as compression. When the bell moves backwards, it creates a region of low pressure known as rarefaction. As the bell continues to move forward and backward, it produces a series of compressions and reactions. This makes the sound of a bell propagate through the air.
