Answer 1

vibration of a any medium causing egaerness to hear

Answer 2

Hey friend,
Here is the answer you were looking for:
Sound is nothing but a vibration.

Sound needs a medium to travel.

Sound cannot travel without any medium. (By medium, we mean solid, liquid or gas)

Sound cannot travel in vacuum. ( That's why we can't hear anything in space and moon)

But we do talk in space through radio waves.

Sound can travel after in solids than in liquid and gases.

So, this was some basic information about sound.

Hope this information would be helpful to you!!!!
