A nylon guitar string has a linear density of 7.0 g/m and is under a tension of 155 N. The fixed supports are distance D = 90.0 cm apart. The string is oscillating in the standing wave pattern shown in Figure 16-39.a) Calculate the speed of the traveling waves whose superposition gives this standing wave.b) Calculate the wavelength of these traveling waves.c) Calculate the frequency of these traveling waves.
