Microwave ovens

Various bits of info about microwave ovens and resonance frequency of water:

The chart near the bottom of this page shows that microwave oven wavelengths
are not near any sort of resonance frequency of water:

Search for "resonance" on this page:

Here is info on how microwave ovens work (basically h2o is polarized and the
field makes them rotate):
http://www.zyra.org.uk/microw.htm


This one doesn't mention 'resonance' but explains how the polar nature of
water is used to make microwave ovens work:

This one talks about how the frequency of microwave ovens was chosen:

Another mention of polar and resonance frequency (search for "resonance")
