A stringed musical instrument produces sound through the vibrations of strings fixed at both ends.  If the velocity at which waves propagate through each string is known, what information is needed in order to determine the fundamental frequency of each string?A.String bulk modulusB.String lengthC.String densityD.String cross-sectional area

Suppose the fundamental frequency of a string is 880 Hz. Which of the following frequency pairs is both the harmonics of the fundamental frequency, whose frequency ratio forms a fifth? (I) 1760 Hz (II) 2640 Hz (III) 3520 Hz (IV) 3960 HzQuestion 13Select one:A.(I) and (III) onlyB.(II) and (IV) onlyC.(I) and (IV) onlyD.(I) and (II) onlyE.(III) and (IV) only

A 1.5-m string is held fixed at both ends. When driven by a 180-Hz source, the string vibrates in 3 distinct segments. What is the natural fundamental frequency of the string?Select one:a.60 Hzb.30 Hzc.90 Hzd.540 Hz

.The frequency of the note produced by plucking a given string increases as

A speaker and frequency generator are used to create resonances in two pipes.  Pipe A of length L is open at both ends.  Pipe B is also of length L but is closed at one end.  Which statement about the fundamental frequencies produced by the pipes is true?A.The fundamental frequency of pipe A will be twice as great as the fundamental frequency of B, because antinodes must occur at open ends and nodes must occur at closed ends.B.The fundamental frequency of pipe A will be half as great as the fundamental frequency of B, because antinodes must occur at open ends and nodes must occur at closed ends.C.The fundamental frequencies of the pipes are the same, because the speed of sound is the same in both pipes.D.The fundamental frequencies of the pipes are the same, because all pipes of equal length will resonate at the same frequency.
