Calculate how much original energy the oscillator in will have left after three cycles.
Using Q= (ω/Δω)
I have calculated the Q factor to be 4
The answer can be obtained by using the equation
Where ΔE/E is the fractional energy loss per cycle of the oscillation
The Attempt at a Solution
I have been advised that I do not need to work out the original energy, instead, work out what % or fraction of the original energy is left.
I tried using Q/2π which gave me an answer of 0.64, however the question asks over 3 cycles. Didn't know what to do after that. Fairly sure Q/2π isn't right anyway!
Any pointers would be much appreciated.
