RESULTS 1. Using the measured values of L in equation 2. calculate the wavelengths 2. for each of the standing waves n=3 through n=9 and record the results in the Calculations Table 2. From the measured values of m, calculate the tension from T = mg. For the value of g, use 9.80 m/s2. Record the values of T in the Calculations Table. 3. Calculate the values of VT for each of the values of T' and record them in the Calculations Table +. According to equation +. should be proportional to VT with 1/f/u as the constant of proportionality. Perform a linear least squares fit to the data with 2 as the ordinate and VT as the abscissa. Calculate the slope of the fit and record it in the Calculations Table.Equate the slope to 1/1/4treating f as an unknown. Using the known value of J, solve the resulting equation for f. Record that value of the frequency as fexp in the Calculations Table. Also calculate the correlation coefficient of the fit and record it in the Calculations Table. 5. Calculate and record the percentage crror of fexp compared to the known value of the frequency f = 50 Hz 6. Make a graph of the wavelength as the ordinate and VT as the abscissa. Also show on the graph the straight line obtained from the linear least squares fit to the data. a 7 Standing Waves on a String I= m u= 3x10* kg/m Results Table
