What does vacuum mean in sound?
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 in.
Is there a sound in vacuum?
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.
What is a vacuum in science sound?
Sound cannot be heard in a vacuum, because there are no air particles to vibrate and carry it. Sounds can travel through some materials, but a closed door will reduce noise, as the sound is reflected.
What happens to sound in vacuum?
Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound.
Can a bell move in a vacuum?
A vacuum is created within the jar whilst the bell is ringing. Once a near vacuum has been created, the bell cannot be heard as sound cannot travel through a vacuum.
Why can’t you hear a bell in a vacuum?
The solution is radio waves. Radio waves travel perfectly fine through a vacuum because they are a type of electromagnetic wave (light), and electromagnetic waves do not need a medium to travel through. Because of this vacuum, you can no longer hear the bell jingle until you allow air to enter the bottle.
How fast does light travel in a vacuum?
300,000 kilometers per second
Surprisingly, the answer has nothing to do with the actual speed of light, which is 300,000 kilometers per second (186,000 miles per second) through the “vacuum” of empty space.
How does a sound wave travel in a vacuum?
Mecanical “sound” waves will travel through everything in contact (more or less efficiently depending of the quality of the contact and materials). In the vacuum if you let the fork touching your skull (through your skin), or your helmet, you would ear it. Air is not the only support for sound ! Highly active question.

What is the definition of a vacuum in science?
In science, a vacuum is defined as space without matter or air. That’s the simple definition, but the truth is that there are always still some particles of matter in a vacuum, but many, many less than the air you’re breathing.
