A standing wave pattern is created on a string with mass density μ = 3.1 × 10-4kg/m. A wave generator with frequency f = 69 Hz is attached to one end of the string and the other end goes over a pulley and is connected to a mass (ignore the weight of the string between the pulley and mass). The distance between the generator and pulley is L = 0.67 m. Initially the 3rd harmonic wave pattern is formed. What is the wavelength of the wave?
