How do we know that alternate compressions and rarefactions are formed in air when a sound propagates in air which is just a similar case of formation of compressions and rarefactions in a slinky when a longitudinal wave propagates through the slinky? Is there any experiment to prove the truth of formation of compressions and rarefactions when a sound propagates in air?

Dear student,

ompression is a higher than normal air-pressure, rarefaction is lower than normal air-pressure.

together these two elements make up a sound wave, which is what we hear when something is hit or played.

if you look at any normal visual representation of a soundwave, the humps above the middle line are called compression, the humps below, rarefaction.

Dear sir

Good noon,

My question actually was how will we prove experimemtally THAT ALTERNATE COMPRESSIONS AND RAREFACTIONS are formed in any material say air when a sound wave travells through the material just like we see in a slinky when we make to vibrate the slinky in a horizonal surface. I hope  you will be kind enough to suggest me any experiment. Thanks a lot.
