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

Answer»

COMPRESSION and refraction are PRODUCED as a result of disturbance in the medium such as water

Explanation:

  • These disturbances are CAUSED by sound waves
  • The sound waves propagate with the help of these refraction and compression
  • The particles of the medium start vibrating and create disturbances
  • These disturbances MAKE the particles of the medium come CLOSER to each other
  • Particles go further each other; more dense particles create compression and less dense create refraction
