Approx 300000000 metres per second in vacuum.
Light always travels at the speed of light, although that's a different number in different substances.
The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
A asteroid travels at the speed of light.
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.
No, not quite. The sound travels at the speed of sound to your ear.
It only travels in the speed of light
No, electricity does not travel at the speed of light. The speed at which electricity travels depends on the medium it is passing through. In most cases, electricity travels at a fraction of the speed of light.
Light is much faster then the speed of sound. Sound travels at a speed of about 768 Miles per hour, when light travels at a speed of 186,282 miles per SECOND.
A tachyon
they both travel at the same speed ? :>)
Ultraviolet light travels at a greater speed than infrared light. This is because the speed of light is constant in a vacuum, and different wavelengths of light, such as ultraviolet and infrared, have varying frequencies and energies.
In vacuum it travels at 299,792,458 metres per second.
