Does anyone happen to know what's the resonant frequency of water
molecules? I'm having a lot of trouble finding it on google.

Hint: Microwave ovens operate on the principle of exciting resonant
vibrations of water molecules.

Sorry, but I have to disagree with this one. They operate on the
principle that lossy conductors get hot in an applied field.

Yes, that's true, but the 2.4GHz frequency is also matched to a set of
resonant frequencies in water, sugars, and oils:

That's why that frequency is chosen.

Actually that part of the spectrum was designated for industrial
machinery because water absorption at those frequencies makes it
unhandy for things like communication and radar.

When microwave ovens came along they were dumped in there because
they are concidered industrial machines.
