Is vacuum a medium of light?
Light can travel through vacuum, but it is not a medium.
What type of light waves can travel through a vacuum?
Light spectrum is part of the electromagnetic radiation spectrum. Electromagnetic waves travel better and faster (light speed in vacuum) in vacuum.
How does light change speed from glass to air?
In glass, light will go somewhat slower than in a vacuum. Air is almost like a vacuum, with respect to the speed of light - some difference still exists, though.In glass, light will go somewhat slower than in a vacuum.

Can light behave as a particle or as a wave?
It can act as both
Who said light can behave as a particle or a wave?
Albert
Is vacuum a medium of light?
Light can travel through vacuum, but it is not a medium.
Why doesn't light travel through a vacuum?
Light does travel through a vacuum.
The speed of light indicates how fast light can travel in a vacuum?
Yes ... in a vacuum.
How does light behave when reflected?
relaxed
Does light travel at its slowest speed when passing through a vacuum?
No, light is at its fastest in a vacuum.
What happens when light passes through vacuum?
it travels at c (speed of light in a 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.
How does the speed of light change as light change as light moves from a distant star toward earth in the vacuum of space?
As long as it remains in the vacuum in the vacuum, the speed of the light doesn't change at all.
Do all vacuum tubes light up?
No, there are some cold cathode vacuum tubes. These do not light.
How does light behave when it interactes with matter?
as a photon
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.
What evidence do we have that light travel through a vacuum?
You create a vacuum in a lab, and then shine a light through it, and there is experimental proof that light travels through a vacuum. Alternatively, take the fact that light travels through space - if light could not travel through a vacuum, no light from the stars, the moon or the sun would ever reach our planet.
