a vacuum, since there is nothing for the light to hit and be slowed down.
just out of interest, the slowest is frozen crystaline sodium, where light travels at 38mph
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 (photons) will usually travel fastest.
Sound travels fastest through a nonporous solid medium, such as steel.
solids
According to the table the medium that sound travels at fastest speed is the electromagnetic waves.
Light can travel with and without a medium.
Light (photons) will usually travel 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.
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.
Sound travels fastest through a nonporous solid medium, such as steel.
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.
solids
Sound waves travel fastest through solids. *Generally, sound waves travel faster as the density of the transmission medium increases.
All electromagnetic radiation in a given medium (water, air, vacuum, etc) travels at the same speed, the speed of light in that medium.
Light can travel with and without a medium.
Light can travel through vacuum, but it is not a medium.
According to the table the medium that sound travels at fastest speed is the electromagnetic waves.
Light travels fastest in a vacuum.
