How does the speed of microwaves compare to the speed of visible light when measured in a vacuum?
They are equal.
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 speed of visible light compare with the speed of gamma rays when both speeds are maeasured in a vacuum?
If both of them are in the same substance, then their speeds are equal.
How does the average speed of light glass compare with its speed in a vacuum?
About 2/3 its speed in a vacuum.
What is the speed of light in miles per second in a vacuum?
The speed of light is 186,000 miles per second in a vacuum.
How does the speed of microwaves compare to the speed of visible light when measured in a vacuum?
They are equal.
What does c equal in the speed of light?
"c" in this case means the speed of light in a vacuum. This is approximately equal to 300,000 km per second.
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.
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.
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.
What happens to frequency does the speed of light ever change?
The speed of light IN A VACUUM is always the same. In substances other than the vacuum, the speed of light is usually slower than in a vacuum.
In a vacuum all electromagnetic waves have?
In a vacuum, all electromagnetic waves have the same speed, which is the speed of light (approximately 3.00 x 10^8 m/s).
How does the speed of visible light compare with the speed of gamma rays when both speeds are maeasured in a vacuum?
If both of them are in the same substance, then their speeds are equal.
What is the speed of light of a vacuum?
In vacuum, the speed is 299,792,458 meters per second.
How does the average speed of light glass compare with its speed in a vacuum?
About 2/3 its speed in a vacuum.
What percentage of the speed of light in vacuum is the speed of light in water?
The speed of light in water is about 75% of the speed of light in a vacuum. This is due to the higher refractive index of water, which slows down the speed of light as it passes through the medium.
What is the speed of light in miles per second in a vacuum?
The speed of light is 186,000 miles per second in a vacuum.
