    The experiment has not been done yet. I am not sure where to get the value for lambda? 146 Sound Resonance in a Tube Overview Sound waves are considered longitudinal waves. That is, the molecules (air molecules for instance) will oscillate about their equilibrium positions in the direction of the wave (disturbance). If a tuning fork vibrates and held over an open ended tube, which is closed at the bottom, it will send a sound wave down the tube. This...
