Which is a comparison of the speed of light in a material compared to the speed of light in empty space?
The speed of light in any material medium is less than it is in empty space.
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 do you calculate speed of light in a vacuum?
-- look up the electrostatic permittivity of free space -- look up the magnetic permeability of free space -- multiply them -- take the square root of the product -- take the reciprocal of the square root The number you have is the speed of light in a vacuum.
What is the speed of light in a vacuum such as space in equation form?
The Equation is:c = K where'c' = the speed of light'K' = a constant = 299,792,458 meters/second
How does the average speed of light glass compare with its speed in a vacuum?
About 2/3 its speed in a vacuum.
