Despite what you see and hear in films and on TV, what we call sound cannot travel in a vacuum. A material medium (like air) is required.


By the way, this concept was behind the tag-line for the original "Alien" film: "No one can hear you scream in space."

How fast can sound travel through a vacuum?

Sound cannot travel through a vacuum as it needs a medium, such as air, water, or solid material, to propagate. In a vacuum, there are no particles for sound waves to travel through, so the speed of sound is essentially zero.


How does the speed of sound change in a vacuum?

sound can not be in a vacuum because a vacuum has no air. Sound needs a medium to travel though. :)


Does sound travel up or down in a vacuum?

Sound does not travel in a vacuum because it requires a medium, such as air or water, to propagate. In the absence of a medium, there is no material for sound waves to travel through, so sound cannot travel up or down in a vacuum.

The velocity of sound in vacuum is?

The velocity of sound in vacuum is 0 m/s because sound requires a medium, such as air or water, to travel through. In the absence of a medium, sound waves cannot propagate and therefore, there is no velocity of sound in vacuum.


Is the velocity of sound at its maximum in a vacuum?

No, sound cannot travel through a vacuum because it requires a medium, such as air or water, to propagate. In an environment with no medium, like a vacuum, sound waves cannot travel and therefore do not have a velocity.
