Consider a guitar string that has a tension of 90 N, a length of 65 cm, and a mass per unit length of 7.9 × 10^–4 kg/m. What is the fundamental frequency of the string? That is, what is the frequency of the standing wave with the lowest possible frequency? What note does this string emit when played open (i.e., without being held against a fret)? You may want to consult a table that gives musical notes and their corresponding frequencies for standard tuning.
