Quizplus · Accepted Answer

Resonant vibration occurs at frequencies that are integer multiples of the fundamental frequency. For a fundamental frequency of 500 Hz, the resonant frequencies would be 1000 Hz (2nd harmonic), 1500 Hz (3rd harmonic), 2000 Hz (4th harmonic), etc. Therefore, 1500 Hz can set the string into resonant vibration.
