All waves in the electromagnetic spectrum travel at 3x108 ms-1 or 300000000 metres every second.
No, that is not true. In a vacuum, all electromagnetic waves travel at the same speed.
Any electromagnetic wave can travel through space, and they all do.
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
All electromagnetic waves travel through space at the "speed of light". Light is one form of electromagnetic waves.
basically an empty space with no particles etc, but all the electromagnetic waves can travel through it
No, that is not true. In a vacuum, all electromagnetic waves travel at the same speed.
All electromagnetic waves travel at the speed of light in a vacuum.
Their speeds are all the same.
All electromagnetic waves travel at the same speed.
Radio-waves, like light, are electromagnetic waves and hence travel at the speed of light.
Any electromagnetic wave can travel through space, and they all do.
speed?
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
All electromagnetic waves, including radio.
All electromagnetic waves travel through space at the "speed of light". Light is one form of electromagnetic waves.

They all have the same speed of travel.
