Sound cannot travel through a vacuum, it needs a medium to travel through as its the vibration of particles that allows its energy to progress

Why can't sounds travel in a vacuum?

because sound waves are vibrations, and in a vacuum, there is nothing for the sound to go through.


Sound can travel through a vacuum is it true or false?

False. Sound requires a medium, such as air, water, or a solid material, to travel through. In a vacuum where there is no medium, sound cannot travel.


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. :)


Is it true that sound waves can travel through a vacuum?

No, sound waves cannot travel through a vacuum because they require a medium (such as air, water, or a solid material) to propagate. In the absence of a medium, there is nothing for the sound waves to travel through, so they cannot propagate.


What does not make sound?

A vacuum does not make sound. Unlike a vacuum cleaner, which does!


If two people were in a vacuum could they hear each other speak - This is a hypothetical question and assumes a true vacuum.?

No. Yes, provided it is a vacuum that they could survive. A true vacuum in which there is no matter of any kind is a real stretch of physics, and only really exists in theory. What we call a vacuum is really just a strong negative pressure. Matter is still present. Even in the "vacuum" of space, there's still some matter.Answer No. Sound waves will not travel through a vacuum. There is a physics lesson explaining why in detail on this website http://www.physicsclassroom.com/Class/sound/U11L1a.html


How fast is the speed of sound in a vacuum?

The speed of sound cannot be measured in a vacuum because there is no medium for sound waves to travel through in a vacuum. Sound requires a medium such as air, water, or solids to propagate.


Can sound travle to space?

Space is a vacuum. Sound cannot travel in vacuum


Can people here sound in space?

No. Sound is the vibration of air. Sound will not travel in a vacuum. Space is a vacuum


What happens to the sound waves when it enter into vacuum?

Sound waves cannot propagate in a vacuum. Sound waves travel through matter, and a vacuum is, by definition, the absence of matter.


Where is there no sound?

There is no sound in space or a vacuum.


If a tree fell in a vacuum why wouldn't you hear a sound?

Sound does not travel through a vacuum.
