16.6 Exercise 16

Two sinusoidal waves with identical wavelengths and amplitudes travel in opposite directions along a string producing a standing wave. The linear mass density of the string is $\mu = 0.075 \text{kg}/\text{m}$ and the tension in the string is $F_{T} = 5.00 \text{N} .$ The time interval between instances of total destructive interference is $\Delta t = 0.13 \text{s} .$ What is the wavelength of the waves?
