Question

theeric · Answer

Electromagnetic waves are made up of electric and magnetic waves. Neither wave seems to need a medium to travel through.

A good example is the radiation from the Sun. What we get is electromagnetic, and it has traveled along a long path through space - which is nearly a vacuum.

The presence of x-rays, gamma rays and deterministic waves from deep space and the transmission of man-made extraterrestrial signals from vehicles on Mars are examples of electromagnetic waves traveling through a vacuum.
