Above 20GHz you mean.

  Nope, about 2ghz

    that was chosen to build smaller ovens, not because of a "resonating frequency".

  Microwave oven is about 2.45 GHz, and I agree it's not optimal for heating water. But the middle of the free 2.4GHz to 2.5GHz band.

    yes, but it has nothing to do with a resonance frequency.
