# Electromagnetic spectrum

I understand that the electromagnetic spectrum is made up of different frequencies of light waves, but is this true in all cases such as with longer wave frequencies? "such as with microwaves". sometimes I get the impression that with microwave ovens for example use waves of electrons, so my question is, is there some kind of threshold where somewhere between infrared to microwaves does the frequency makes the conversion from light to electrons? (and if so, how?) or is it always light and has some other correlation such as light influencing the electrons thru the air?

No, it's always light. Microwaves use light. They do, however, use electron motion to generate that light. –  DumpsterDoofus Feb 25 '14 at 4:43
ok, I need an explanation for this down vote, its A genuine question, did I ask it wright? –  GammaRay Feb 25 '14 at 4:45
I didn't downvote, it was probably someone else. Maybe they downvoted because of the misconception that long-wave radiation is electrons? –  DumpsterDoofus Feb 25 '14 at 4:46
no not you, I didn't see your comment till I submitted mine. –  GammaRay Feb 25 '14 at 4:48
DumpsterDoofus-thanks for the answer, that's what I figured, if only you could have answered me in the answer box I could have up voted it. –  GammaRay Feb 25 '14 at 4:52
