sound can not be in a vacuum because a vacuum has no air. Sound needs a medium to travel though. :)

How fast is the speed of sound in a vacuum?

Sound waves cannot travel in a vacuum.


What is faster than a bullet?

* The speed of light in a vacuum, * The speed of sound,


Compare the speed of light to the speed of sound?

Assuming you mean the speed of sound in air, the speed of light (in a vacuum) is about 800,000 times larger. However, sound has very different speeds, depending on the medium in which it travels.Assuming you mean the speed of sound in air, the speed of light (in a vacuum) is about 800,000 times larger.

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 many times faster is the speed of light in a vacuum than the speed of sound air?

100% - sound is vibration of atoms/molecules - it cannot travel through vacuum ___________________________ The idea of "speed pf sound in a vacuum" is meaningless; sound cannot travel without a medium such as air, water, metal, stone, or SOMETHING. Sound waves are mechanical vibrations; there has to be something to vibrate. The speed of sound in air is around 700 miles per hour, while the speed of light is 186,000 miles per SECOND.

How does the speed of light change as light change as light moves from a distant star toward earth in the vacuum of space?

As long as it remains in the vacuum in the vacuum, the speed of the light doesn't change at all.

Does the speed of light change in a vacuum?

No, not as long as the light stays in vacuum.No, it does not. That is where it has its maximum speed.


Why is the speed of sound slower then the speed of light?

The sound needs a medium to be transported. Without that medium (vacuum) there is no sound. The sound is blocked by air mulecules. The light does not need a medium.
