1. How does the sound produced by a vibrating object in a medium reach your ear?
Ans:
When an object vibrates, it causes the surrounding particles of the medium (such as air) to vibrate. These vibrations create a series of compressions and rarefactions that travel through the medium. The sound is transferred from one particle to the next until it reaches your ear, where it is detected by the eardrum.
2. Explain how sound is produced by your school bell.
Ans:
When the school bell is struck with a hammer, it starts vibrating. These vibrations create compressions (regions of high pressure) and rarefactions (regions of low pressure) in the surrounding air. These sound waves travel through the air, and we hear the sound of the bell.
