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.
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.
outer space
Violet
No, light is at its fastest in a vacuum.
Light travels fastest through empty space.
Red travels fastest Violet slowest.
Light (photons) will usually travel fastest.
Speed of light is fastest through vacuum. Although it is only about 0.001 times slower in air.
Air
because there is nothing in space to block the light and no barometric pressure
Light travels fastest in a vacuum with an approximate speed of 3.0 * 108 ms-1.
