The fundamental frequency in each of two vibrating systems is 400 Hz. For each ofthese systems, (below), calculate the two lowest frequencies (excluding the fundamental)at which standing waves can occur.(i) a string fixed at both ends and(ii) a cylindrical pipe open at both ends

A pipe of length L is closed at one end. Another pipe is open at both ends and has length 2L.What is the lowest common frequency for the standing waves in the pipes?

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.

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

An open organ pipe has a fundamental frequency of 300 Hz. The first overtone of a closed organ pipe has the same frequency as the first overtone of the open pipe. Find the length of each pipe. (velocity of sound = 330 m/s)0.45 m and 0.3125 m0.42 m and 0.7615 m0.35 m and 0.85 m0.55 m and 0.4125 m

A 20.0 cm long organ pipe is filled with air and is open at one end and closed at the other. The speed of sound in air at 0°C is 331 m/s. What is the frequency of the fundamental mode?
