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

[@radhika20011]

legends seeing the 12 hours before exams

[@naseerahmad4111]

Explained nicely

[@ayyanfaisal4762]

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.

[@surendraram3808]

Thankyou sir ❤

[@prathaviraj5907]

fine

[@neelurana6076]

I am also Physics teacher nice explanation

[@hamaraprash7199]

sir my doubt is how in gravity movie the explosion happen if there is no oxygen then how explotion happen because we need fuel, oxygen and air to burn any thing so how in space vacuum will the explosion will happen?

[@interestingworld1389]

when to decide rarefaction and COMPRESSION??

[@user-kb3qw4jf4d]

compression is crest, rarefaction is trough

[@ranvirt3231]

I want teachers like you in school then i eilll top in my class

[@besti9449]

sir i have a doubt that the bat use the echo for location this is called the echolocation and if the marine water animal also use this method how because if the light absored by water but why sound never absorbed by water pls clear the doubt

[@user-kb3qw4jf4d]

sound is made when a boy vibrates. this pushes the atoms near it, creating waves. these waves pass on the energy

[@ajaylakshmipandey7858]

Sir when a ball goes in the pound and we throw the stones then the ball to use and your saying that the object floting in water do not move.

[@magnusgiftspvt.ltd.7515]

sir i have doubt

[@rama.nationz]

[@AditiAradhya-sk1xr]

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

[@prardhanab9102]

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]

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😊
