John ties a 15-m-long, 5 kg rope to a wall and stretches it out horizontally, placing it under a tension of 2000 n, which gives the rope a wave speed of 77.5 m/s. he then creates a wave in the rope by oscillating one end.
a) what is the frequency of the third harmonic for this rope?
b) what is the fundamental frequency of this rope?
c) what is the frequency of the third harmonic for this rope?
