Question: You have a string with a mass of 0.0127 kg. You stretch the string with a force of 8.13 N, giving it a length of 1.81 m. Then you vibrate the string transversely at precisely the frequency that corresponds to its fourth normal mode, that is, at its fourth harmonic.
Part A: What is the wavelength of the standing wave you create in the string?
Part B: What is the frequency?
Please show steps to determine the wavelength of the standing wave you create in the string.
