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.
Hence, Sound cannot travel through vacuum, but it requires a medium.
Where can sound not travel?
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.
Does sound travel if there is no medium?
So no medium, as in vacuum, means no waves of a medium, and therefore no sound. That’s because sound is a mechanical wave. Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic waves require no medium, but can still travel through one.
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.
What happens to air particles when sound travels through it?
When the sound wave travels in air it causes the air particles to actually act as a medium between the source and listener. Its causes rarefaction and compression of air particles and force them to carry certain sound energy and due to this the sound travels in air and it makes you to intake it and listen the sound .
Does the sun make noise?
The surface of the Sun produces sound waves because the surface is convecting and this produces pressure waves that travel into the inner corona. But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles!
How quiet is space?
Outer space or ‘space’ is defined as the void that exists between celestial bodies including the earth. The earth’s atmosphere is distinct from outer space since it is gravitationally held by the earth itself. At such pressures, sound cannot propagate in outer space, and hence space is quiet.
Do you need air to hear?
A: Sound can’t be carried in the empty vacuum of space because sound waves need a medium to vibrate through such as air or water. However, because the particles are so spread out, the sounds waves they produce are at such a low frequency, humans are incapable of hearing them.
Can you hear sound 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.
Can sound travel 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. 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.
Can a sound kill you?
The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.
Can light travel forever?
Answer 3: If there were no objects to absorb light, it would keep traveling forever. Light is made up of particles called photons that travel like waves. If it is infinite, the light would travel forever.
Do sound waves ever die?
To answer your question, yes. Sound waves do die out after a while. When this vibrational energy is absorbed by objects in space, the energy of the wave starts reducing ultimately making is so low that the resulting sound is inaudible, and the sound finally dies out.
