Astanding wave pattern is created on a string with mass density μ = 3 × 10-4 kg/m. a wave generator with frequency f = 65 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 = 0.74 m. initially the 3rd harmonic wave pattern is formed.
1) what is the wavelength of the wave? m
2) what is the speed of the wave? m/s
3) what is the tension in the string? n
4) what is the mass hanging on the end of the string? kg
5) now the hanging mass is adjusted to create the 2nd harmonic. the frequency is held fixed at f = 63.0 hz. what is the wavelength of the wave? m
6) what is the speed of the wave? m/s
7) what is the tension in the string? n
8) what is the mass hanging on the end of the string? kg
9) keeping the frequency fixed at f = 63.0 hz, what is the maximum mass that can be used to still create a coherent standing wave pattern?
