Question

Describe with the help of a diagram, how compression & rarefaction are produced in air near a source of sound.

Answer 1

Hi friend ,

When a vibrating object moves forward ,it pushes and compresses the air in front of it creating a region of high pressure . This region is called compression . This compression starts to move away from the vibrating object. When the vibrating object moves backwards,it creates a region of low pressure called rarefaction .As the object moves back and forth rapidly ,a series of compressions and rarefactions is created in the air.

Hi there !!


<>When an object is struck hard , it starts to vibrate.

<> The object starts to vibrate in forward and backward directions

<> The vibrating body , starts to move forward.

<> As it moves forward , it creates an area of high pressure.

<>This area of high pressure is known as compression

<>Also , when the object moves backward , it creates an area of less pressure around it surroundings .

<> This area of low pressure is known as rarefaction.

<> It moves forward and backward as a series of
alternate compressions(C) and rarefactions.(R)

<> The object continues to move forward in the form of alternate compressions and rarefactions.
