You have been invited to design an adjustable sound tube for a concert hall. The orchestra wants the tube to be able to produce sound at two different fundamental frequencies: one for open tubes and another for closed tubes. To carry out this project, you should: a) Describe how vibration and the formation of standing waves work in open and closed sound tubes. b) Calculate the length of the tube needed to achieve a fundamental frequency of 440 Hz with a sound velocity of 340 m/s in the case of an open tube. c) Calculate the fundamental frequency of a closed tube of the same length as found in item b) and with the same sound velocity.
