Light travels fastest in pure vacuum, at the speed of light of 299 792 458 m/s (670,616,629 mph).
If there are any particles, some light will reflect off of those particles and bounce around, reducing its speed. With combinations of certain gasses, it is possible to slow light down to extremely low relative speeds. Scientists have even managed to stop a beam of light for a fraction of a second.
Light moves fastest in a vacuum (like space). All wavelengths of light (including visible, ultra violet, infra red, x-rays, etc) move at the same speed, 3.0*10^8 m/s in vacuum.

Light travels fastest in empty space, not air. It doesn't have to fight through molecules while traveling.

Which travels fastest through a medium a photon atom sound or electron?
Light (photons) will usually travel fastest.
Which medium would sound travel the fastest?
Sound travels fastest through a nonporous solid medium, such as steel.
What medium do sound waves travel fastest in?
solids
According to the table in which medium does sound travel at the fastest speed?
According to the table the medium that sound travels at fastest speed is the electromagnetic waves.
Can light be transmitted with or without a medium?
Light can travel with and without a medium.
Which travels fastest through a medium a photon atom sound or electron?
Light (photons) will usually travel fastest.
What color water does light travel through fastest?
According to the light spectrum, water should travel through a more violet coloured water the fastest. The speed of light through a medium is not governed by its wavelength, so colour is not a factor.
When is the only time that light waves travel at thespeedof light?
Light waves ALWAYS travel at the "Speed of Light"....based on the medium that the waves are traveling through. It just so happens that they go the FASTEST in a VACUUM.
Which medium would sound travel the fastest?
Sound travels fastest through a nonporous solid medium, such as steel.
What medium do sound waves travel fastest in?
solids
Does light waves travel fastest through empty space?
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
In what medium does sound travel fastest - solid -liquid - or gas?
Sound waves travel fastest through solids. *Generally, sound waves travel faster as the density of the transmission medium increases.
What EM radiations travel the fastest from its source?
All electromagnetic radiation in a given medium (water, air, vacuum, etc) travels at the same speed, the speed of light in that medium.
Is vacuum a medium of light?
Light can travel through vacuum, but it is not a medium.
Can light be transmitted with or without a medium?
Light can travel with and without a medium.
According to the table in which medium does sound travel at the fastest speed?
According to the table the medium that sound travels at fastest speed is the electromagnetic waves.
In which medium is the speed of light a maximum?
Light travels fastest in a vacuum.
