Light travels fastest through a vacuum. After that it travels fastest through air since it is almost the same.
Light travels fastest through space which has no air. Space is a vacuum which is the fastest way for light to travel.
Light travels fastest through vacuum.
No, light is at its fastest in a vacuum.
Yes it is
Light travels fastest through empty space.
Light travels fastest through a vacuum. Traveling through air, glass, or any other material slows it down.Free space
Red travels fastest Violet slowest.
Light travels most quickly through empty space.
Light (photons) will usually travel fastest.
Speed of light is fastest through vacuum. Although it is only about 0.001 times slower in air.
light travels fastest through aire because it is less dence then water or glass, when light travels throught water it slows down
Light travels fastest in a vacuum. Other than that, it would travel fastest in a very dilute (low-pressure, and therefore low-density) gas.
it travels faster through glass it travels faster through glass
empty spaceLight travels fastest in empty space, not air. It doesn't have to fight through molecules while traveling.
because there is nothing in space to block the light and no barometric pressure
# vacuum, fastest # air, next fastest # water, next slowest # glass, slowest
Light waves travel fastest through vacuum, at nearly 30 million meters per second. Light travels more slowly through other substances such as air and water, and can be absorbed.
Light travels fastest in a vacuum with an approximate speed of 3.0 * 108 ms-1.
In a vacuum.
The answer to "What is the fastest thing that can travel?" is light. Light can travel faster than any other thing in the universe!
