Can sound travel through a vacuum Why or why not?
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. ... Radio is a form of electromagnetic radiation just like light and can therefore travel through the vacuum of space just fine.
Can you hear yourself talk in space?
Just in brief: - When we speak we generate sound waves. Sound waves needs some atmosphere to carry them, so in ISS or in space suit atmosphere is created artificially, hence they can hear their self voice in space suit.
Can light travel in a vacuum?
Light is an electromagnetic wave that does not require a medium for transmission. ... Because of this light does not require a medium for propagation. They can travel through a vacuum.
What can sound Cannot travel through?
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
Why can't astronauts hear each other in space?
One can't hear in the vacuum of space because sound doesn't travel through vacuum, it needs a medium. ... Those are inside the helmet, which contains air and thus a medium for sound. The radio signal is able to travel from one astronaut to another, through the vacuum of space because it isn't a sound wave.
Can a sound wave travel in the vacuum of space?
Sound waves cannot travel in the vacuum of space because there is no medium to transmit these mechanical waves. Classical waves transfer energy without transporting matter through the medium.
Why is there no sound in a vacuum?
This is illustrated with reference to a hand bell, a humming bird and buzzing insects. 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 is the speed of sound in a vacuum?
The speed of sound in a vacuum is zero meters per second, as sound cannot travel in a vacuum. Sound is a wave, which means it spreads through the vibration of particles in a medium, such as water or air.
Can a light wave travel through a vacuum?
Light can travel in vacuum but sound cannot. This’s because sound waves are vibrating waves (also called pressure waves ) travel by physical contact of molecules. No, sound waves cannot travel through a vacuum; they require a physical medium to travel through (e.g. air, wood).
