How fast does light travel in a gas and why?
The speed will depend on the type of gas and on its density.
What are mediums for light waves?
Light is considered a self-propagating wave. So it does not need a medium, which is why it reaches the earth from the sun. The mediums which dont absorb the light (and therefore allow light to travel through it) depend on the wave length of light. For example a gamma ray (has a very short wavelength) can travel through metal and takes a block of lead to absorb it.
When light enters a medium with a different refractive index they change speed or direction?
yes , if the light travel from less density to more density the speed will decrease , the direction will change depend on the entered angle
Who can we say light does not need to travel in medium?
how can we say light does not need light to travel
How long would a message take if you are 6 light-years away from earth in minutes?
Light-year is the distance that light travels in a year. Therefore, it will take light 6 years to travel 6 light-years. So far, it has not been possible to send messages faster than the speed of light, and it will probably never be possible (read about the Theory of Relativity to get an idea about the reasons for this).
Does light travel at low speeds?
Normally, the answer to that kind of question would depend on what you call "low".In the case of light, however, probably nobody would call it a 'low' speed, becauseit's physically impossible for anything in creation to travel faster than light in a vacuum. It is possible for things to travel faster than light does in other media, but it's not exactly common, and it's still very much on the "fast" end of the scale.
How light will travel from medium air to silver?
Light will not travel into silver.
What can light travel in?
Light can travel in a vacuum or in any transparent material
How far in Light years can a Pulsar travel?
As far as light can travel
What do you need to travel at the speed of light?
There is no way to travel at the speed of light.
How fast does light travel through copper?
Copper is opaque to light - light can not travel though it.
If you could travel at the speed of light and you looked in a mirror would you see your reflection?
That would depend on your speed relative to the mirror. If you were holding it in front of you, yes. If it was stationary and you were passing it, no.
