The angular frequency formula is correct. --AxelBoldt

Hmm. Sorry, didn't check this page before, I just changed it back. With my browser/settings, formulae look much better like this:

v = ω / k = λf ,

than like this:

  v = ω / k = λf .

But that's just for me. Feel free to change it back. -- DrBob
