In which medium sound travels faster air steel water vacuum?

Answer 1

Sound travels faster in a denser medium, so sound travels most rapidly in steel. However, since sound is a longitudinal wave it is medium dependent, meaning that a medium must be present. Since a vacuum is basically defined as a lack of medium, sound will not travel at all ('No one will hear you scream in space'). This is different from light which travels slowest in solids and fastest in air or vaccuum.

Answer 2

Sound needs always a medium for transportation. Therefore in a vacuum in outer space we cannot hear a sound, like they play us in Science Fiction films.

The speed of sound depends on the medium in which it is transported.

The speed of sound is slow in gases, like in air.

The speed of sound is faster in liquids, like in water.

The speed of sound is fastest in solids, like in metal.

Answer 3

SOLID

The speed of sound will depend on the stiffness and density of the medium, and will be faster in a low density material with a high stiffness.

c = sqrt( K / p )

c = speed, K = bulk modulus (stiffness), and p = density

Solids are generally the stiffest and least dense materials, but some solids may have slower sound speeds than some liquids. For example, the speed of sound in lead (soft and dense) is lower than the speed of sound in water (softer, but much less dense).

On the surface of Earth, the fastest medium is diamond, which has a very high stiffness and a low density.

The material with the absolute fastest sound velocity is metallic hydrogen, which has a stiffness roughly equal to diamond, but has about 1/4th the density of diamond. Of course, metallic hydrogen could only be found in places with extreme pressures, such as the surface of gas giant planets or the center of the Sun.

Answer 4

The speed of sound in steel is faster than the speed of sound in air , water , and vacuum.

Sound is a vibration that travels through an elastic medium as a wave.

The speed of sound in a material depends on the elasticity of the material .

Elasticity is the ability of a material to change shape in response to an applied force, and then resume its initial shape once the distorting force is removed.

In elastic materials , the atoms are relatively close together and respond quickly to each other's motions , transmitting energy with little loss.

Steel is very elastic. If there is no medium-as in a vacuum- there will not be sound transmission. Note: as temperature increases, the speed of sound also increases. Medium------------------------------------------------------Speed of Sound Air (sea level standard conditions) -----------------> 340 m/s, or 343 m/s

Water (fresh water) -----------------------------------> 1435 m/s, or 1433 m/s

Steel ------------------------------------------------------> 5100 m/s, 6100 m/s

Answer 5

Sound requires a medium in which to travel. Sound cannot travel in a vacuum.

Sound travels pretty well in a metal, and will diminish in intensity according to how much is dampened in the material. The metal with the highest sound velocity is Beryllium, in which its velocity is almost 13 km/sec.

Answer 6

The speed of sound in air, of which 78% is nitrogen ~ 340 m/s

in water ~ 1560 m/s in steel ~ 6000 m/s Hence, steel is the winner.
