D Divya Prakash Singh

When the school bell vibrates, it pushes the adjacent particles of air to vibrate. This causes the disturbance in the wave when the bell moves forward it pushes the air particles in front of it and creates a region of high pressures known as compression and when the bell moves backwards, it creates a region of low pressure known as rarefaction.

The continuous forward and backward movement of the bell produces a series of compression and rarefaction. This makes the sound of a bell to propagate through the air.
