Question

True or false:

1. An oscillator with resonance frequency wo will always oscillate at a frequency wo in response to a driving force.

2. If an oscillator is driven at its natural frequency it oscillates in phase with the driving force. If I plot the amplitude of the response of a driven oscillator A(w) as a function of the drive frequency w, the full width at half maximum of that curve will be (wo/Q) where wo is the oscillator's resonance frequency, and Q is its quality factor.

3. If I plot the amplitude of the response of a driven oscillator A(w) as a function of the drive frequency w, the full width at half maximum of that curve will be (wo/Q) where wo is the oscillator's resonance frequency, and Q is its quality factor.

Explanation / Answer

1.False

It will not always oscillate at resosnance frequency for ay value of driving force

2.True

Reason

At w=wn

we get state of resonance

3.True

We will get

full width=wo/Q
