Question

Describe with the help of a diagram, how compressions and rarefactions are produced in air near a source of sound.

Answer 1

Answer:

When anything is set to vibration, it produces sound. Question 2: Describe with the help of a diagram, how compressions and rarefactions are produced in air near a source of sound. Answer: Compression and rarefaction are produced because of the disturbance in medium caused by sound wave.

Answer 2

$\red {HELLO\:DEAR}$

• When a vibrating body moves forward, it creates a region of high pressure in its vicinity.
• This region of high pressure is known as compressions.
• When it moves backward, it creates a region of low pressure in its vicinity.
• This region is known as a rarefaction.
• As the body continues to move forward and backwards, it produces a series of compressions and rarefactions (as shown in the following figure).
