Taking measurements from Figure 1, determine the value of Q for each of the oscillators represented. Explain how you obtained your answer. I haven't made an attempt as answering this as i'm unsure where to start. Any suggestions would be appreciated.
The rate at which the mass–spring system loses energy to its surroundings is referred
to as the Q-value for the oscillator. The Q-value is defined as:
Q= 2π (E \ ΔE)
ΔE/E is the fractional energy loss per cycle of the oscillation
This can be expressed in terms of angular frequency as:
Q= (ω/ Δω)
or frequency as:
Q= ( f/ Δf)
where Δ ω and Δ f are the width of the peak at its halfway point.
