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

### Is the speed of sound equal to an electromagnetic wave?

No, speed of sound in air is much slower than the speed of light in vacuum.

### 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 ultrasonic waves in vacuum is equal to what is the speed of audible sound in air?

No, ultrasonic wave do not travel at all in 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.

### 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.
