A guitar string that is 0.474m long oscillates in the third harmonic (third smallest frequency). These oscillations emit a sound that travels at a speed of v = a resonance tube that has one end open and one end closed, to set up a standing wave in the resonance tube. The wavelength of the sound wave in the tube is = 0.327m, and it is the 4th longest wavelength. (The following questions will be marked correct only if your answer is within 1% of the correct value.) What is the speed of the displacement wave in the string? m/s 342.08m/s towards A 0.16m long wire with linear mass density of = 4.08 10kg/m is under tension T = 103N between two fixed ends. When struck, it produces a n = 5 harmonic note that travels through the air and sets up a standing pressure wave inside an air tube that is open at both ends so there are pressure nodes at each end of the air tube. The speed of sound in the air tube is 343.4m/s. If the standing wave in the air tube has 5 pressure nodes, what is the length of the air tube? m
