Hey guys quick question ...

Can u explain this to me???

I know that 'the frequency of the sound is the same as the frequency of the vibration of the source of the sound' but i dont understand why????

Someone explain please?

sound energy is formed when an object vibrates, this causes the air molecules next to the object to vibrate at the same frequency.
