A typical steel B-string in a guitar resonates in its fundamental frequency at 240 Hertz. The length of the string is 0.600 m. What is the wave velocity along the string? = 2.88×102 m/s The tension in the above string is 84.0 N. Calculate the mass of a 3.00 m long piece of the steel string. Find the wavelength of the third harmonic of the guitar string.
