Answer:

They all move at the same speed in a vacuum.

Step-by-step explanation:

All electromagnetic wave travel with the same speed in vacuum. This speed is equivalent to 3x10^8m/s

All electromagnetic wave have different frequencies and wavelengths. The frequency and wavelength are in inverse proportionality i.e as the frequency of a wave increase, its wavelength decreases. The same is also applicable to the energy of waves. Each electromagnetic wave have different energy.
