Use a laptop as a mobile wireless power meter
Just because EMR is in the microwave band, doesn't mean it will warm food. The 2.4 GHz and 5 GHz frequencies that wireless routers operate on are actually in the microwave band of 300 MHz to 300 GHz, the microwave band is a subset of the radio band of 3 kHz to 300 GHz.
Use a laptop as a mobile wireless power meter
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? |
