Explain how sound is produced by your school bell.
Open in App
Solution
When
the school bell vibrates, it forces the
adjacent particles in 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 pressures known as compression.
When the bell moves backwards, it creates a region of low pressure
know as rarefaction. As the bell continues to move forward and
backward, it produces a series of compressions and rarefactions. This
makes the sound of a bell propagate through air.
