Hey all,
just wondering over a very naive question but I couldn't really find the answer by looking through the web. So electromagnetic waves are self sustaining and they don't lose energy while traveling through space, except if the photons they're made out of do "collide" with matter which doesn't give off radiation at the same frequency and wavelength and the original photon's energy gets transformed into heat/kinetic energy. So what would happen if you would operate a microwave oven with the door open and stand right next to it? (asuuming that was possible) Would you heat up as well? Or would the waves/photons just be absorbed by air molecules and heat them up before they reach you? Sounds stupid but I was very interested in that ^^
And furthermore, if I may add this related question: How come then that radio/television waves are transmitted over such a large distance without first being absorbed. Something to do with the longer wavelength?
thx very much
