If particles do not move with the wave then do,actually the compressed or the rarefaction particles move with the wave together?

Sir what is the difference between inversely proportional and directly proportional cause My teacher taught me... but I didn't understand... please tell ???

@prardhanab9102 11 ай бұрын

It is like when frequency increases then pitch also increases this is called directly proportional another example for this is when frequency decreases pitch also decreases ( basically together)

@prardhanab9102 11 ай бұрын

And for inversely proportional it means basically the opposite from directly proportional such as if A is going up and B is going in the opposite direction ( down ) then its inversely proportional ...hope this was helpfull😊

Sir but actually sound travels fastest in solids because the particles are tightly packed when a molecule or particle vibrates it causes the particles next to them to vibrate as well hence the particles in solids are held in a framework sound spreads quickly as compared to liquids and gases in which particles are far from each other.
