electromagnetism - Are EM radiation and EM waves the same thing?





  1. Are EM radiation and EM waves the same thing? I have seen this topics treated separately in many books. It is still not clear to me whether EM radiation and EM waves are synonymous. Is there any difference?




  2. Another question: When one says that EM waves are solutions of Maxwell equations on vacuum does this mean that there is no charge at all in any point of space?
