Spoken sound waves use air to travel along. As a vacuum does not contain any air particles, sound will not be heard.
Sound is mechanical energy, and it requires a mechanical medium to propagate. That means that the medium must behave or respond in some mechanical way to conduct sound. Air or any liquid or solid will respond mechanically to the compression and rarefaction of a sound wave. In a vacuum, there is nothing to be compressed, so no sound will be conducted.
Because a vacuum does not have a medium (material) for the sound waves and particles to pass through the same with space because there is no air for them to travel through.
it does not travel in a vacuum because the molecules do not have any air
<><><><><>
Sound travels by vibrating the medium, i.e. air. Without a medium, sound cannot travel.
No. It requires a medium to transport vibrational energy from one location to another. Sound waves are carried by the vibrations of matter, such as our atmosphere or anything solid. A vacuum has no matter that could vibrate.
Interestingly enough, two astronauts in space CAN communicate by sound. If they touch their helmets together (or if both of them were to touch their helmets to a solid bar) the solid matter WOULD carry the sound, as vibrations in the material structure. The vibrations in the helmet would then cause vibrations in the air inside the helmet, and the astronaut could hear.
This is the same principle that kids have used for 100 years to build a "tin cans and a string" telephone.
No, because sound travels as the result of the vibration of particles. As vacuums are completely void of matter, vibrations can't be induced to carry sound.
No. Sound waves must have a medium like air, water or even steel in which to travel. Waves propagate by one particle bumping against the particle next to it and so on until it reaches an ear or something that can register the waves. Although outer space is not a perfect vacuum there are to few particles to keep up continues bumping.
No.
Sound waves rely on molecules of gas, liquid, or solid (matter) to propagate, and a vacuum contains none of those things.
Because sound needs an median to pass through and in space there is no median. In explanation: sound can actually be heard better through some objects than others, such as through water rather than air.
The short answer is NO. Sound requires some form of gas to be present so that the vibrations can be picked up. A vacuum has no gasses. However if in a vacuum you touch helmets of a spacesuit together you can here each other. This is solely because both suits contain gases and the vibrations are passed through the helmet not through the vacuum.
Sound is one example of a mechanical wave. Others are waves in water,
and waves along strings and ropes. All of these need material stuff to move
through. If there's no material stuff, these waves don't go anywhere. There
is no material stuff in space to carry mechanical waves.
Because sound is made from vibrations and vibrations cant travle through empty space
It does not. Sound needs particles to be transmitted. Vacuum does not have particles.
Sound travels through what is called a medium, a medium can be anything made of matter and a vacuum has no medium preventing sound from traveling
Because sound travels through air molecules, by vibration. There is no air in space or in a vacuum.
No: worst. Sound cannot travel though a vacuum.
Sound waves don't just travel the slowest in a vacuum, they don't travel at all. The reason is that sound waves, like all mechanical waves, need a medium to travel through.
No, ultrasonic wave do not travel at all in a vacuum.
Sound waves cannot propagate in a vacuum. Sound waves travel through matter, and a vacuum is, by definition, the absence of matter.
The vacuum does not produce sound waves nor, can sound waves travel through them. A sound wave needs something to travel on/through, such as air. A vacuum doesn't contain any particles required for sound waves.
The sound not travel through vacuum because sound need a medium to travel.
Sound cannot travel through a vacuum.
It is told that sound cannot travel trough vacuum. Sound can only travel through medium.
vacuum
Space is a vacuum. Sound cannot travel in vacuum
Sound waves cannot travel in a vacuum.
Sound travels faster through a solid than through a vacuum. In a solid, sound waves propagate through the material's molecules, leading to faster transmission. In a vacuum, there are no molecules to transmit sound, so it cannot travel at all.
sound can not be in a vacuum because a vacuum has no air. Sound needs a medium to travel though. :)
Sound needs a medium through which to travel. It will not travel in a vacuum.
sound can't travel through a vacuum. or a place without air.
No, sound cannot travel in a vacuum. Sound moves by vibrating particles of a solid, liquid, or a gas. Since there are no particles in a vacuum, sound cannot travel through it.
Sound does not travel through a vacuum.
