A typical steel B-string in a guitar resonates in its fundamental frequency at 240 Hz. The length of the string is 0.680 m. The wave velocity is 326.4m/s.
a) The tension in the above string is 84N. Calculate the mass of a 3m long piece of the steel string.
b) What is the wavelength of the third harmonic of the guitar string described above?
