How do sound waves travel through media?

Answer 1

Sound waves travel through vibrations. If one particle starts vibrating it will pass on that movement to other particles that are close by. This means that sound travels quickly through solids as the particles are closely packed and readily pick up movement from their neighbours; it travels less quickly through liquids as the particles are close enough to pick up vibrations but not tightly packed like they are in solids; sound travels slowest through gases (weird, but true - even though we rely on gases to pass on the sounds we make in speech) because their particles are much further apart.

If there are no particles - like in a vacuum such as you'd find in space - then sound can't travel at all!

Answer 2

Sound waves need a medium, however, ocean waves are simply water traveling in an undulating pattern. On Earth, ocean waves are caused by the tidal patterns created from the sun & moon's gravitational pull on the Earth. Sound waves are audible energy that bounces off of particles, making it medium-dependent.

Answer 3

Sound travels through matter of any state, solid, liquid, gas or plasma, as long as the matter's molecules are close enough to interact with each other. The denser the matter, the easier and faster sound travels through it. Sound cannot travel through a vacuum or near-vacuum, like space, but it can be converted into variations in an electo-magnetic carrier wave, which can be transmitted through space then converted back to sound.
