The speed of light is a constant, C= 300,000 km per second.
They are equal.
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.
If both of them are in the same substance, then their speeds are equal.
About 2/3 its speed in a vacuum.
The speed of light is 186,000 miles per second in a vacuum.
They are equal.
"c" in this case means the speed of light in a vacuum. This is approximately equal to 300,000 km per second.
The speed of light is equal to 1 unit of c, where c is the speed of light in a vacuum, approximately 299,792 kilometers per second.
No, speed of sound in air is much slower than the speed of light in 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.
No, not as long as the light stays in vacuum.No, it does not. That is where it has its maximum speed.
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 the same speed, which is the speed of light (approximately 3.00 x 10^8 m/s).
If both of them are in the same substance, then their speeds are equal.
In vacuum, the speed is 299,792,458 meters per second.
About 2/3 its speed in a vacuum.
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.
