Greetings to everybody!
I have 2 microwave ovens. On the back of the old one, it states that =
the Operating Frequency is 2450MHz(2.45GHz). The newer one has nothing =
on it. Do all microwaves operate at 2.45GHz, and if so, why? Is this =
supposed to be the electrical resonance of water as I have heard. I =
don't see how it can be, because in the Scientific American Explorations =
issue for this quarter on the study of Intelligence, it states that =
water resonates around 1.4-1.5GHz. I need clarification as to why the =
microwave would be that much higher for freq. Thanks.

P.S. If anybody can think of any uses for the power supply out of the =
old one (it is a 650Watt unit), ideas are welcome. Thanks again
