Ok - here goes: I see the energy levels of the harmonic oscillator as E = hw(n+1/2) = hwn + hw/2 (please ignore the lack of cool symbols) Now the hw/2 is something called the ground state - fine - no problem. Should I interpret hw as the fundamental harmonic? 2hw as the second harmonic? nhw as the nth harmonic? etc? etc? Does this mean that the frequency of the harmonic oscillator is increasing as n increases?
