## Can sound travel through a vacuum Why or why not?

Sound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work on it.

## What happens when sound waves enter a vacuum?

Sound propagates by causing the particles in the medium to vibrate. A vibrating source transfers the vibrations to the surrounding medium, which can be solid, liquid or gaseous. In a vacuum, there are no particles that can transfer and carry vibrations, so sound cannot travel.

## Can a light wave travel through a vacuum?

In contrast, light waves can travel through a vacuum, and do not require a medium. In empty space, the wave does not dissipate (grow smaller) no matter how far it travels, because the wave is not interacting with anything else. In this case, some light is absorbed and lost as heat, just like sound.

## Can shock wave travel through a vacuum?

A ‘shock wave’ is the disturbance of material that’s created when a wave moves through a medium at greater than the local speed of sound. Provided there is a ‘medium’ of sufficient density through which a shock wave can travel, there is no reason why shock waves can’t form in space.

## Can you hear yourself talk in space?

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.

## Why can’t you hear a bell in a vacuum?

In the vacuum of space, there are no (or very, very few) particles to vibrate, so sound cannot travel through this medium. Because of this vacuum, you can no longer hear the bell jingle until you allow air to enter the bottle.

## What can sound not travel through?

## Why can we not hear any sound on the moon?

You cannot hear any sound on moon. “Sound” is actually vibrations in the air or let’s just say a medium. Sound can travel in the atmosphere of the moon, which is space, because the gases in it can propagate sound just like the air on earth transmits it, but we certainly cannot hear it.

## Do sound waves go on forever?

Sound waves do not live forever. As the energy of the sound is transferred to more and more molecules of air, they vibrate less and less until the effect is lost in the constant random jostle of air molecules. The sound is gone.
