A nylon guitar string is fixed between two posts 1.50 m apart. The string has a linear mass density 5.20 g/m of and is placed under a tension of 160.00 N. The string is placed next to a tube, open at both ends, of length L. The string is plucked and resonates at the fundamental frequency while the tube resonates at the n = 1 mode. The speed of sound is 343 m/s. a)What is the velocity of the wave on the string in m/s?

b)What is the fundamental frequency of vibration of the string in Hz?

c)What is the length of the open-ended tube in meters?
