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.
In a vacuum the speed of ultraviolet radiation is faster than the speed of light?
no
Why is it impossible for the index of refraction to be less than 1?
The index of refraction, defined as the ratio of the speed of light in a vacuum to the speed of light in a medium, cannot be less than 1 because light travels fastest in a vacuum. If the index were less than 1, it would imply that light travels faster in the medium than in a vacuum, which contradicts the fundamental principles of physics. Additionally, this would violate causality, as it would suggest that information could be transmitted faster than the speed of light.
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?

Can anything travel faster than the speed of light through a vacuum?
No.
