Radio waves, light, X-rays, and some cosmic rays — they all belong to the same family. They travel at the velocity of light.
The wave has both electric and magnetic components which are bound together. At the end of its travel the wave gives up energy. The ether waves are those we know as wireless waves.
When the waves are too long they are "seen" as infra-red, when they are too short they are "seen" as ultra-violet. Shorter than thе ultra-violet are X-rays and far shorter than the shortest of these  are the  "gamma"  rays,  and  finally the cosmic rays.
