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.

What is faster than a bullet?
* The speed of light in a vacuum, * The speed of sound,
Which is fastest sound or light waves?
-- In vacuum, the speed of sound is zero, so you can't compare them there.-- In air at sea level, the speed of light is about 874 thousand times the speed of sound.
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.
Conconde flies faster than the speed of light?
No. The Concorde flew faster than the speed of sound. Nothing can move faster than the speed of light.
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.

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.

What travels faster out of sound and light?
Light is roughly a million times faster than sound. (Speed of light in a vacuum: 300 million meters/second; speed of sound in air: ca. 350 meters/second; the speed of soundin other substances varies quite a lot.)
Why was light from the rocket seen before the sound of rocket was heard?
Because light travels significantly faster than sound. Speed of light (in vacuum) = 299 792 458 m/s Speed of Sound (at sea-level ) = 340.29 m/s
Why is the speed of light limited in a vacuum?
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.
How much faster does the speed of light travel than the speed of sound?
Speed of light in vacuum is 299792458 m/s or 983571056.43045 ft/s.Speed of sound in air of 20°C or 68°Fahrenheit is 343 m/s or 1125.32808 ft/s.You see that light is 874030 times faster than sound.
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.
How fast travel light can travelwich is faster light or sound?
Light is usually much, much faster. The speed of light (in a vacuum) is about 300,000,000 meters/second. The speed of sound varies a lot, depending on the medium; but in dry air, at a temperature of 20°C, it is about 343 meters/second.
How much faster does the speed of light travel than the speed of sound a simple answer?
The speed of light in vacuum is 299,792,118 meters/secondfaster than the speed of sound at sea level.That's about 186,282 miles per hour faster.The speed of light is roughly 874 thousand times faster than the speed of sound.I hope that's simple enough for you.
Should the speed of light in water be faster that the speed of light in a vacuum?
No, it shouldn't. And it isn't.
Is the speed of light or sound faster?
The speed of light is about 880 thousand timesfaster than the speed of sound.
