Question: A machine tugs sideways on an elastic rope with a frequency of 4.5 Hz. A graph of the transverse displacements of this rope wave at t=1.0s as a function of position is shown below.
a. What is the velocity of waves on this rope?
b. If the frequency of the machine tugging on the rope is doubled to f = 9.0 Hz yet the tension in the rope remains the same, what is the new wavelength of waves on this rope? What is the new velocity of waves on this rope?
