Q: There is an acoustic resonance, which echoes is the fixed resonance when it is in vibration.
  • A. whistle
  • B. tuning fork
  • C. electric circuit
  • D. clarinet
Correct Answer: Option B - The tuning fork is an acoustic resonance that echoes a fixed resonance when it in vibration. The frequency at which the tendency to oscillate with the highest amplitude is found, that frequency is called the resonance frequency. Resonance phenomena is associated with all types of vibrations or waves.
