2.7GHz f = c / λ - λ = 11E-2m and c = 3E8m/s

freq = c/wavelength = 1.58 x 10^9 1.58 GHz.

frequency = (3x10^8 m/s)/(0.19 m) = 1.6 x 10^9 Hz.

Any one of these answers may be correct as it depends on many different factors which are not included in your rather silly question.

Well it is as sill as asking
"What is the best time to eat bananas"................. Oh! and the answer to that is:
"While you are still up in your tree"

? the idea is to heat the water - so it's the resonant frequency of water. see above for the numbers.

here's a web link for some detail:

It's a spambot testing its posting rights.

I've met Ian Kendal and he is not a spambot. I'm not sure about Jonathan.

I met Jonathan. He was not a spambot, but it was a long time ago.

Rule 35? If there's a website for it you can also find spambot postings?
