A nylon guitar string has a linear density of μ= 4.88 g/m and is under tensionτ= 144 N. The fixed supports are D= 90.8 cm apart. The string is oscillating in the standing wave pattern as shown in the figure. Calculate the frequency (in Hz) of the traveling waves whose superposition gives this standing-wave pattern.
