The D-string on a properly tuned guitar produces a tone with a fundamental frequency of 146.8 Hz. The oscillating length of a D-string on a certain guitar is 0.69 m. This same length of string is weighed and found have a mass of 1.4×10-3 kg.   At what tension, in newtons, must the D-string must be stretched in order for it to be properly tuned?  What is the wavelength, in meters, of the standing wave in the D-string when it is oscillating at its third harmonic (also called its second overtone)?  Determine the frequency, in hertz, of the third harmonic of the tone produced by the properly tuned D-string.
