wavelength and frequency of the tenth harmonic for the M=0.100 kg case? 3. According to the data of Data Table 2, if the tension is increased, how did the wave speed and the first harmonic change? 4. If the length between wave generator and pulley is 0.4 m and linear mass density of the string is 4.0 g/m, what are the tension and the hanging mass values to produce one loop of standing wave with f1 = 8 Hz
