A standing wave pattern is created on a string with mass density = 0.00035 kg/m . A wave generator with frequency f = 62 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 = 0.59m. Initially the 3rd harmonic wave pattern is formed.a) What is the wavelength of the wave? _______________mb) What is the speed of the wave? ______________m/sc) What is the tension in the string? ________________Nd) What is the mass hanging on the end of the string? ________________kge) Now the hanging mass is adjusted to create the 2nd harmonic. The frequency is held fixed at f = 62 Hz. What is the wavelength of the wave? ________________mf) What is the speed of the wave? ______________m/sg) What is the tension in the string? ________________Nh) What is the mass hanging on the end of the string? ________________kg
