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 0.075 kg/m and the tension in the string is 5.0 N. The time interval between instances of total destructive interference is 0.13 s. What is the wavelength of the waves?

A string, fixed on both ends, is 7.50 m long and has a mass of 0.130 kg. The string is under a tension of 112 N. The string is vibrating to produce a standing wave at the fundamental frequency of the string.

A standing wave is produced on a string by two sinusoidal transverse waves that are identical but moving in opposite directions. The string is fixed at and . Nodes appear at , 3.00 m, 6.00 m, 9.00 m, and 12.00 m. The amplitude of the standing wave is 2.50 cm. It takes 0.15 s for the antinodes to make one complete oscillation.
