They can travel at the speed of light.

All electromagnetic waves propagate at c in vacuum. They do not all have the same wavelength (the spectrum ranges from radio to gamma), they can travel through vacuum (not only through matter), and their electric and magnetic fields are oscillating (not nonmoving).
