The speed of light is different in different substances ... air, water, glass, jello, etc.
The speed of light is fastest in a vacuum. All other media slow the speed of light down, albeit very slightly.
When light travels through anything that is not a vacuum, it will usually slow down.
Yes, light does slow down when it travels through matter, as it interacts with atoms and molecules in the material. This slowing down of light is responsible for effects like refraction and dispersion.
Silicon, with an index of 3.96, is the lowest I could find.
No; a denser medium will slow the light down. When the speed of light is quoted, unless otherwise stated, it is implied that it's through a vacuum. The primary example of this is the speed light travels through water or glass. The different speeds are what create the rainbow effect, essentially splitting the light by slowing down different wavelengths at a different rate.
No, it is not possible to slow down the speed of light in a vacuum.

In some special substances, it was possible to slow the speed of light to just a few meters per second - incredibly slow compared to the speed of light in a vacuum.In some special substances, it was possible to slow the speed of light to just a few meters per second - incredibly slow compared to the speed of light in a vacuum.In some special substances, it was possible to slow the speed of light to just a few meters per second - incredibly slow compared to the speed of light in a vacuum.In some special substances, it was possible to slow the speed of light to just a few meters per second - incredibly slow compared to the speed of light in a vacuum.
Time does not stop at the speed of light; rather, time appears to slow down for an object moving at the speed of light relative to an observer.
Yes. Light goes slower in water.
Yes, light does slow down when passing through different mediums. This is due to the interaction of light with the atoms and molecules in the medium, which causes the light to change speed.
It dosent unless you are traveling the speed of light it slow's down. The sun going down isnt time.
When light waves enter water, they slow down. This change in speed is due to the difference in the refractive index between air and water, which causes the light to bend as it moves from one medium to another.
I think you mean slow down and speed up. slow down =slow, speed up=fast
Light will slow down if it goes through just about anything that is not a vacuum, for example air, glass, water.
Light slows down in water because it interacts with the molecules in the water, causing it to change direction and speed. This interaction results in a decrease in the speed of light as it travels through the water.
As long as light -- another name for electro-magnetic radiation -- does not change what it is going through, there is no reason whatsoever for it to slow down. Why should it?
