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.
About 2/3 its speed in a vacuum.
The speed of light is 186,000 miles per second in a vacuum.
In a vacuum the speed of red and blue light are the same as all light, 300,000,000m/s. Their frequency and wavelength will be different but the speed remains the same.

Yes, electromagnetic waves travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. This speed is a fundamental constant of nature and is denoted by the symbol "c".
No, not as long as the light stays in vacuum.No, it does not. That is where it has its maximum speed.
In a vacuum, the speed of an electromagnetic wave, such as light, is constant at approximately 299,792 kilometers per second (or about 186,282 miles per second). This speed is denoted by the symbol 'c' and is a fundamental constant of nature.
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.
The speed of an electromagnetic wave in a vacuum is a fundamental constant of nature, denoted by the symbol 'c'. The value of the speed of light in a vacuum is approximately 299,792,458 meters per second. This value is derived from the properties of free space and the relationship between electric and magnetic fields in vacuum.
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.
The speed of light is 186,000 miles per second in a vacuum.
Yes ... in a vacuum.
