Through Which Medium Does Sound Travel Fastest?

Sound travels faster in water than in the air� but in solids it travels about eight times faster. Sound is basically a longitudinal wave, which means it has to have a medium to travel through. For sound to travel quickly then it can only do this by the medium in which it is travelling through compressing and then expanding very, very quickly. So in effect, the denser a medium is, the quicker the sound will be transmitted. Gases will usually transmit sound much more slowly than liquids and solids because of this. The lower the density of the gas then it will be even poorer as a medium for conducting sound.

In the air sound will generally travel at around 300 metres per second, whilst in liquid it travels at about 1500 metres per second. If however, it is travelling through solids, then this increases to 2500 metres per second.

Sound travels faster through solids than through liquids and gasses (air) because the molecules are packed much tighter.  With each sound wave vibration, the molecules in solids don't have to move much because they are so close together.  However, gasses and liquids have molecules set farther apart, so the molecules have to go longer distances to "bump into each other."

Solid

Sound travels at the fastest speed in steel.

Steel

Solid

Solids because they are the most dense

In solids
it travel faster in a hot surface, the particles move faster
if the solid is cold its slower the movement.

Solid

Solids, as they have the densest mediums, compared to liquids and gases.

Liquid

Iron

If you think it's wrong you should correct it.

Liquid

Sound travel faster through air
