Light is an electromagnetic wave.
All types of electromagnetic wave travel at the same speed,
as long as they're traveling through the same stuff.
The speed is 299,792,458 meters per second in vacuum, and
somewhat slower in any material. The exact speed depends
on the material, and it's different for every material.
They don't. Nothing can exceed the speed of light. Electrons in a television travel much slower than the speed of light.
They can ONLY move slower than the speed of light.
There is no way to travel at the speed of light.
It moves at a slower speed!
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
No, light in a medium will travel at a slower speed.
They don't. Nothing can exceed the speed of light. Electrons in a television travel much slower than the speed of light.
The speed of light is approx 299792458 metres per second. And it does not travel any faster nor slower in the US.
Yes. The speed of light in a vacuum (or space) is 3x10^8 m/s. Light will travel slower in any other medium.
Speed of light is max. in vaccum and slower in air.
No. Because of their mass, they travel slower than c.
900 billion years - if you travel near the speed of light. If you travel at any slower speed, it will take longer of course. But do some reading on time dilation - if the traveller travels at a speed very near the speed of light, from his point of view it will take much less time.900 billion years - if you travel near the speed of light.

Speed of light is fastest through vacuum. Although it is only about 0.001 times slower in air.
They can ONLY move slower than the speed of light.
slower than the speed of light
Light can certainly travel slower than its speed in vacuum ... 299,792,458 meters per second.It travels slower than that whenever it's traveling through anything other than vacuum, such as air, water, glass, jello, etc.Light slows when it travels through any material medium. In fact, the speed of light in a medium is equal to the speed of light in a vacuum divided by the index of refraction of the medium.
What is the speed of light? About 300,000,000 meters per second - enough to travel all around the Earth 7.5 times in one second. Can anything travel nearly as fast? - Yes, in particle accelerators particles are regularly accelerated to over 99% of the speed of light. According to current scientific understanding: (a) it is not possible to transfer matter, energy, or information faster than the speed of light. (b) An object that regularly travels at a slower speed can't be made to travel at the speed of light - it can only approach it. (A photon, that is, a speed of light, can only travel at the speed of light.)
