SUMMARY
The vibrational frequency of a guitar string can be determined using beat frequencies produced when sounded with tuning forks. In this discussion, a guitar string produces 4 beats per second with a 350-Hz tuning fork and 9 beats per second with a 355-Hz fork. The solution involves applying the relationship between beat frequency and the difference in frequencies of the two sound sources. The calculated vibrational frequency of the string is 351 Hz, derived from the average of the frequencies of the tuning forks adjusted for the beat frequencies.
