You missed the answer that was given, "the photons at 1 GHz have only 4.136e-6 eV of energy." That is the role they play. If you want more about those photons, Each one carries a small amount of the energy (about 1 KW) out of the magnetron. The oscillating field in that resonant cavity mentioned earlier is coupled into the waveguide that leads to the 'heating area' where those photons excite vibrations in the water molecules in the food, heating the food. And as I said, the path the electrons take, the fact that microwaves are gnerated by the motions of the electrons and the length of time it takes for the electrons to spiral out from the cathode to the anode are all inconsistent with BaTH. -- bz please pardon my infinite ignorance, the set-of-things-I-do-not-know is an infinite set. bz+spr(a)ch100-5.chem.lsu.edu remove ch100-5 to avoid spam trap

Yes they are Henry, all your ballistic effects are frequency independent, and you know that or you would have attempt to say _why_ not.

Yes I do, but you told me you omitted it from your program because it is negligible. > You don't include da/dt... If you understood schoolboy calculus, you would know that da/dt has no effect. George

I have a Netgear router and a 100Mb network on cat5 cable. Vista is incompatible with the router (less than a year old) and someone I know got 400kb when he tried it. The solution on the Microsoft site is "buy a more modern router". No chance. George |
