Use a laptop as a mobile wireless power meter
Authored by: ALT147 on Apr 11, '10 03:51:26PM
Only microwaves of a specific frequency warm food, because the energy per microwave photon corresponds to a ro-vibronic energy transition in the water molecule.
In fact, microwaves of anywhere from 1 GHz to a few hundred GHz will warm food. See this page for far too much detail. I just thought it odd that the frequency of a microwave oven coincided with channels 7, 8 and 9 of the 802.11 standard. Even though the power levels may be way too low to heat anything (or anyone), surely you'd choose a band far away from any commonplace, powerful source like a microwave oven for the sake of interference?
