Question

Explain how sound is produced by your school bell?

Answer 1

heya..

Here is your answer...

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.

Answer 2

When struck by an air hammer, the bell generates sound, and when hammered by a hammer, the bell begins to vibrate.

What makes a bell sound?

• When the clapper strikes, the bell begins to move back and forth swiftly, or vibrate, pushing the molecules in the air back and forth to generate sound 'waves.'
• To move, sound requires a medium, such as air, which is composed of molecules that vibrate and transport the sound.
• When the particles begin to vibrate, the waves get disturbed.
• When the bell goes ahead, the air particles in front are pushed forward, generating a high-pressure zone known as compression.
• When the electromagnet is turned on, it creates a magnetic field that attracts the iron strip to it.
• The striker hits the gong (bell).
• When the striking arm makes contact with the gong, the contact is broken and the current ceases to flow through the circuit.
