How does the speed of sound change in a vacuum?
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.

Does most wave travel at the same speed?
Not at all. For example, the speed of light in a vacuum is almost a million times faster than the speed of sound in air.
Why is the speed of sound quicker in a vacuum rather than in air?
There is no sound in a vacuum, you need a medium to translate the sound in. Waves on a pond are like sound waves in the air, in this case the water is the medium. Without air there is no sound because there is no medium to translate the sound to your ears.
Which is true about speed of sound in air?
Well speed of sound in air at room temperature is 350 m/s . It depends on the density of the medium. Sound cannot propagate through vacuum. Speed of sound is directly proportional to the temperature of the medium.
Can the speed of sound travel faster than the speed of light?
No. Light in vacuum is roughly 880 thousand timesas fast as sound in air.
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.
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.
How many times greater is the speed of light than the speed of sound?
The speed of sound in air is about 300 meters per second. (320 is closer still). ..The speed of light in a vacuum is 300 000 000 meters per second.So the speed of light in a vacuum (in air it is only slightly different) is about one million times the speed of sound in air.
What is the speed of light and sound in mph?
Speed of light (in vacuum)= approx 671,000,000 mph.Speed of sound (in air at sea level) = approx 760 mph.
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.
