Ratio of the speed of light in a vacuum to the speed of light in a material?
The index of refraction.
What is the index of refraction?
The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium.
What is the ratio of the speed of light in a vacuum to the speed of light in a different medium?
This is called the index of refraction. When light crosses the boundary between mediums (media) with different indices, it is bent (refracted).It's usually defined the other way around ... the ratio of the speed of light in vacuum to its speed in the medium. Since the speed of light is greater in vacuum than in any medium, the number is always greater than 1. It's referred to as the "refractive index" of the medium.
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 does the average speed of light glass compare with its speed in a vacuum?
About 2/3 its speed in a vacuum.
Ratio of the speed of light in a vacuum to the speed of light in a material?
The index of refraction.
The ratio of the speed of light in a medium to the speed of light in a vacuum is called its?
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
What is the index of refraction?
The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium.
Relationship of the speed of light in a vacuum to the speed of light in a medium where it will pass through?
Refractive index is the ratio of speeds.
Compare the speed of light to the speed of sound?
The speed of light is much faster than the speed of sound. Light travels at a speed of about 299,792 kilometers per second in a vacuum, while sound travels at about 343 meters per second in air. This means light travels approximately 874,030 times faster than sound.
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.
If the speed of light in a vacuum is 1.2 times that of the speed of light in a given material what is the index of refraction for that material?
2 (no units)
How many mach are in the speed of light?
The speed of light in vacuum is about 874 thousand timesthe speed of sound at sea level.
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.
How many times is speed of light compared to sound?
The speed of sound is the velocity of sound through a mechanical (elastic) medium. And the difference is between the speed of sound and light is that Light travel faster then the sound.Light traveling through vacuum is roughly 879 thousand timesfaster than sound traveling through air at sea level.
What is farster the speed of light or the speed of sound?
The speed of light is faster than the speed of sound. The speed of light in a vacuum is about 186,282 miles per second, while the speed of sound in air is about 767 miles per hour.
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.
