Does matter help sound travel through an empty room?
By definition, matter is required for sound to exist. Sound waves are transferred by vibration of molecules, which is why sound does not exist within the vacuum of space. In space nobody really can hear you scream.
Why sound of light can't be heard?
Light makes no sound, hence there is no "sound of light", and anything that doesn't exist cannot be heard.
Why must there be a medium for sound to exist?
Sound is a mechanical wave, and mechanical waves need something to travel through.
What are the properties and behavior of sound waves in a vacuum?
Sound cannot exist in a vacuum, as sound is the vibration though a substance, known as the medium. If no medium is present, no sound is transmitted. In a vacuum, there are no or too few air molecules, that means there is no medium for the sound to exist in, thus there is no sound. It is also why you cannot hear much in space, as the molecules or individual atoms in space are so far apart.
Do sound waves exist even if you can't hear them?
Yes, sound waves exist which are not audible to the human ear. Humans can hear sound waves having frequency between 20 - 20,000 Hz. Other all frequencies lie outside our hearing range and are called ultrasonic or supersonic waves.
Does sound really exist if you are deaf?
Interesting question.... If your brain is unable to receive and process sound waves, then I suppose sound doesn't exist to you, but that certainly doesn't mean that sound doesn't exist in general.
Does sound exist in space?
No. Sound needs a medium to propagate.
Why wasn't there sound in silent movies?
The technology did not yet exist for sound.
What sound do purple cows make?
They make no sound because they do not exist.
What are unicorns sound?
Unicorns are unable to make a sound, as they don't exist in real life!

Can light exist before sound?
Light can exist without sound. A fluorescent light is an example of this. But yes, light can exist before sound. Light and sound are created simultaneously by something like lightning. It's just that the light is propagated much faster than the sound. We all know that we see the flash of lightning before we hear the sound it makes, and we can "calculate" the distance to the bolt by simple mathematical means.
Does the i in exist have a short or long vowel sound?
It has a short I sound, and so does the E. (ig-zist).
Why sound of light can't be heard?
Light makes no sound, hence there is no "sound of light", and anything that doesn't exist cannot be heard.
Does sound exist if no one can hear it?
yes..... Some machine will somehow find some noise...... But if ur in a place with no sound then theres no sound =]
Why must there be a medium for sound to exist?

What sound does a gremlin make?
