Please be more specific.
Yes. The more dense the material the slower light travels. Light travels the slowest in diamond at about a third of its normal speed of 300 000 km /s in a vacuum.
The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
Light always travels at the speed of light, although that's a different number in different substances.
A asteroid travels at the speed of light.
No!...Speed of light is the fastest speed possible, but now a new particle called lepton is more faster than light...rather it is has the fastest speed discovered till now.It travels in the same wave as light travels i.e tranverse waves.
The only thing that travels at the speed of light, is light. Light is also said to have no mass, therefore the only way for something to travel at the speed of light is for it to have no mass.
Fiber Optic Broadband is the type of internet connection that travels at the speed of light.
No, not quite. The sound travels at the speed of sound to your ear.
The entire electromagnetic spectrum travels at the same speed. The speed of light.
It only travels in the speed of light
In a straight line. At the speed of light.
