A rope 3.4 m long has a mass of 0.85 kg. The tension in the rope is 51.0 N. A power source at one end sends a harmonic wave with amplitude 1.50 cm down the rope. The wave is extracted at the other end without any reflection.
What is the frequency of the power source if the power transmitted is 118 W?
