Question

Resonance occurs when the driving frequency equals:
  1. A
    Zero
  2. B
    Natural frequency of the system
    Correct
  3. C
    Twice the natural frequency
  4. D
    Half the natural frequency

Correct answer

Natural frequency of the system

Explanation

At resonance, f_drive = f_natural. Amplitude becomes maximum (limited only by damping). Energy transfer is most efficient.
