Can sound waves move through space?
space is a vacuum, and sound can't move through a vacuum.
Why can you not hear in a vacuum?
Sound waves have to have something physical to travel through, such as air or water. There is nothing in the vacuum for the waves to move in.
How are sound waves and eletromagnetic waves different?
Sound waves require a medium such as air, solid, or liquid in order to propagate. Electromagnetic waves do not require a medium for propagation and can move through a vacuum.
What is the speed of sound waves when travelling through a vacuum?
The speed of sound in vacuum is zero. Sound needs a material medium in order topropagate. Since vacuum contains no material medium, sound does not propagate.Therefore, it never moves from the source of the sound, and theSpeed = (distance covered in any time interval) divided by (time to cover the distance)is zero.
How much faster are electromagnetic wave than sound waves?
Electromagnetic waves in vacuum move about 881 thousand timesas fast as sound in sea-level air.
Can sound waves move through space?

Why don't sound waves move in a vacuum?
There is no air for it to travel through

Do sound waves move in a vacuum?
No.
Can sound waves move through any kinds of matter?
Yes. Sound cannot travel in a vacuum.

How do you know that electomagnetic waves can travel through a vacuum?
Electromagnetic waves travel as streams of particles, thus being able to move through a vacuum. For example, light reaches the earth from the sun and other far away stars. You can compare this with sound waves which requires a medium such as air or water to travel through.
Which bell do not produced sound wave the bell in the water or the bell in a vacuum?
the bell in a vacuum, in a vacuum there is nothing for the sound wave to move through
Sound need particles to move does this mean it can travel in a vacuum?
No, they cannot. Sound waves are compression waves (mechanical longitudinal waves). This means they travel through mediums with the particles of the medium vibrating in the same or opposite direction of the wave, as opposed to perpendicular. Therefore, a sound wave needs particles to vibrate/oscillate for it to travel. If there are no particles, it cannot travel. A vacuum is defined by the absence of matter, meaning there are no particles. Thus, sound cannot travel in a vacuum.
Why can light waves travel through a vacuum but water waves cannot?
That is correct. Light is a moving electromagnetic wave, and the energy it contains is carried in the moving electric and moving magnetic components of the wave. Light can move through a vacuum, and it would rather go through that than air or anything else (which scatters the energy). Sound is mechanical energy, and the energy of the sound is transferred into the medium through which it is travelling. As the energy of sound is carried by the medium, the vacuum of space will not support a sound wave.
