# Do sound waves need a medium to travel?

###### Wiki User

Yes.
Yes, sound waves do require a medium to travel through.
Yes.

They are pressure waves - and they need something (medium) to compress and rarefy.
Yes. Sound waves are compression waves. If there's no medium, there's nothing there to compress!

Some waves called mechanical waves e.g sound need a medium to travel through while electromagnetic waves need no medium to travel through e.g light

no they do not, they can travel through vacuums and do not need particles to travel as sound waves do. radio waves are transverse waves whereas sound waves are not

Mechanical waves.For example, sound waves, ocean waves, etc.Many waves need a medium to travel: sound waves, water waves, and seismic waves.Electromagnetic waves do not need a medium.

Sound waves need some form of matter as a medium through which to propagate.

Sound wave do not travel through vaccum as it need medium to travel.

Sound waves need a medium to travel in. You cannot hear anything in space because space is a vacuum.

Mechanical waves such as sound and vibration require a medium in which to travel. Electromagnetic waves such as radio and light need no transmission medium.

Mechanical waves need a medium to travel in

Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .

No, only surface and mechanical waves need a medium, compressional waves can travel through space. (Such as light from the Sun).I think light (EM) waves are the only ones that can travel through a vacuum. Sound waves require a medium.

Sound travels in waves, these waves need a medium to travel through. Think about water in the ocean, without the water, there would be no waves. Same concept.

Sounds are pressure waves - and they need something (medium) to compress and rarefy. Air is one medium, but water, steel, rock and most other substances can have sound waves.In vacuum there is nothing, no medium, so no sound can travel.

Sound waves need a medium in order to propogate. Light waves can travel without a medium. The speed of light is 3*108m/s.

Because waves, such as sound, need to travel through a medium, whether it be water, air, etc. Since in empty space, there is no air, therefore there is no medium to travel in, so sound cannot travel.Sound waves require a medium (solid, liquid or gas) to travel through. They do this by alternately compressing and rarifying the distanced between the atoms or molecules of the medium.

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.

Sound waves need a medium to travel through - the medium may be solid, liquid, or gaseous. Electromagnetic waves (including light) can also travel through empty space.

light waves or electromagnetic waves are transverse and sound waves are longitudinalElectromagnetic waves can be both transverse and longitudinal waves. Transverse waves are like ocean waves. They move the medium perpendicular to the medium which is the substance the wave is traveling on. Longitudinal waves are like a slinky. They compress and rarefact (The coils get close and move away). Longitudinal waves move the medium parallel to the energy.Electromagnetic waves don't need a medium to travel. They can travel on the medium but they don't need a medium to travel through.Mechanical waves need a medium to travel. They can't travel without one.That is why in starwars when the deathstar blows up and your whole room shakes when it does isn't possible because in space there isn't any air! Sound is a mechanical wave, since there isn't any medium there can't be any sound. If you yell in space nothing would happen because there isn't a medium for the sound waves to travel on. You can see light in space because light is an example of an electromagnetic wave which doesn't need a medium to travel.Cranberryhead. :)

Light waves do not need a medium to propagate. Sound waves cannot travel without a medium. Light waves always travel at the speed of light that is 3*108m/s.

radio waves do not need a medium to travel through.

Heat waves are a form of electromagnetic radiation. Therefore, they are transverse waves (oscillate perpendicularly to the direction of propagation) and need no medium to travel through. Sound waves, on the other hand, are mechanical waves, meaning they need a medium to travel through. If that medium is a liquid or a gas, sound waves oscillate longitudinally (in the direction they're traveling). If that medium is a solid, they oscillate both longitudinally and transversely.

Electromagnetic waves such as light and radio waves may travel through free space. That is how we get the warmth and light from our Sun. Pressure waves need a distinct medium in which to travel - in which to generate their pressure. Sound waves would be an example, whough weather patterns also need a medium. Vibration waves such as sound may also travel through a solid.

They need some medium to propagate, as they travel through the agitations in medium

Sound and water waves are mechanical and therefore need a medium. Light is an electromagnetic wave which travels as a particle-wave, so it does not need a medium to travel through.

Sound waves, ocean waves and seismic (earthquake) waves need a medium
