Which one of the following statements concerning standing soundwaves is FALSE?A) For a tube open at one end only, standing waves of oddharmonics are the only ones present.B) For a tube open at both ends, both odd and even harmonicstanding waves are present.C) The fundamental (1st harmonic) has the same frequency for pipesof the same length where one pipe is open at both ends and the other is open only at one end.D) The wavelength of a standing sound wave in a tube isproportional to the length of the tube.E) The frequency of a standing sound wave in a tube is proportional to the speed of sound and inversely proportional tothe length of the tube.
