A guitar string plucked hard and plucked gently sounds the same note because the period is:
AAmplitude bound
BAmplitude fixed
CAmplitude free
DAmplitude tied
Answer & Solution
Correct answer: C. Amplitude free
1. Plucking harder only changes how far the string swings.
2. The time for each swing does not change with that.
3. So the period is independent of amplitude.
