Because it is the resonant frequency of water. Early microwave ovens polluted that frequency band so heavily that no other service used it. Nowadays, microwave ovens don't send out radio waves any more, so the frequencies are available for other services.
Which is a bit of a shame, since the resonant frequency of water is, by definition, absorbed by water, like wet walls or walking water-bags like you and me. Other frequencies would be much better-suited for human cohabitation, but that's historical evolution for you.
- dsr_ 9y ago"Nowadays, microwave ovens don't send out radio waves any more" Every microwave oven I've ever had, including name-brand ones purchased in the last year, sent out loads of interference on one or more wifi channels. This morning I noticed that my connection at the breakfast table was really crappy. The upstairs hotspot likes to change channels every few days, and it had picked 11. When the microwave stopped, everything cleared up, so I forced it to channel 1 and tested with the microwave again. No problems there.
