Questions and Answers

What is resonance?

  • A phenomenon that occurs when an object is at rest
  • A phenomenon that occurs when an object is subjected to an external force matching its natural frequency (correct)
  • A phenomenon that occurs when an object is subjected to an external force different from its natural frequency
  • A phenomenon that occurs when an object is not subjected to any external force

In what systems can resonance occur?

  • Only electrical systems
  • Only mechanical systems
  • Only acoustic systems
  • Mechanical, electrical, and acoustic systems (correct)

What is the resonant frequency of a system?

  • The frequency at which a system tends to vibrate (correct)
  • The frequency at which a system absorbs no energy
  • The frequency at which a system is at rest
  • The frequency at which a system is not vibrating
