Problem 1: Determine String's Linear Density using 'Standing Waves' Experimental Setup (10 points). One end of the string from the post near the motor drive oscillator was tied, and the other end was passed over the pulley and m=1.0 kg mass was hung from it. Using function generator to vary the oscillator's frequency, the appropriate wavelengths were recorded for n=1, 2, 3, 4 modes. Also, for graphing purposes a column of reciprocate of frequency was created as well. (see below): Row Frequency (Hz) 1/Frequency (s) # 1 2 3 4 51.0 101 150 199 Wavelength (m) 0.019608 3.65 0.009901 1.82 0.006667 1.21 0.005025 0.92 a. From your data, using any row (circle the chosen row number in the first column), and from the theoretical formula of waves speed as a function of frequency and wavelength, calculate the wave propagation speed and then string's linear density. For the density you should use another waves speed formula that relates it with the property of medium (string in this case). Think how you can use m=1.0kg mass for this calculation. For credit you must show all steps of your calculation. Your answer must have correct unit(s). [5 pt.]
