Is this not necessarily true of an electrical oscillator, also? [RLC oscillator]
bc wonders about cavity oscillators, also.

the power dissipation.
Constant energy loss per cycle, other things equal = constant QPower dissipation can be reduced by reducing the resonant frequency at
constant energy loss per cycle,
Reduced energy loss per cycle, other things equal = increased Qor by reducing the energy loss per cycle at constant frequency.
Is this what you were hoping for?Is this what you meant?I was hoping there would be comments about the Q in both cases. What you write is very true.
