For instance, the fact that in a vacuum, it moves at the speed of light.For more information about electromagnetic waves, you may want to check (for example) the Wikipedia article about electromagnetic waves.
Electromagnetic waves can travel through empty space.
They all travel at the same speed in vacuum. Their speed is independent of the frame of reference and no particle with mass can reach their speed.
Sound waves require a medium to transfer energy! :)
