Explain how sound is produced by your school bell. How does the sound produced by a vibrating object in a medium reach your ear
Explain how sound is produced by your school bell. When the sound waves travel through the material medium, then the particles of the medium undergo compression and rarefaction. When the vibrating object moves forward , it pushes and compresses the air in front of it creating a region of high pressure. This region is called as compression. When t he vibrating object moves backwards , it creates a region of low pressure called rarefaction . Here, the school bell consists of a hammer and gong is connected to an external source of the current. When the school bell is hit with a hammer, the hammer hits the gong continuously that causes compression and rarefaction in the air. These vibrations travel in the air in the form it starts vibrating(moves backward and forward), a series of compressions and rarefactions is created in the air and these makes the sound waves propagate through the medium as a result sound is produced in the school bell.
