SUMMARY
The forum discussion centers on an experiment measuring AC mains frequency using a sonometer, where an electromagnet vibrated a string. The key finding is that resonance occurs when the natural frequency of the string matches the external frequency, which is achieved by adjusting the string's length. The amplitude of vibration is directly influenced by the string's length, tension, and material properties, confirming that specific vibrational modes are present in a stretched string.
