    help Date WS4 Sound Standing Waves I. A tuning fork is set into vibeation above a vertical open tube illed with water as shown. The wat level is allowed to drop slowly. As it does so, the air in the tube above the water level is heard to monate with the nning fork when thedstance tom the ope to he water level is at25m and again at 0.375 m.

    The water level in a vertical glass tube 1.00 m long can be adjusted to any position in the tube. A tuning fork vibrating at 693 Hz is held just over the open top end of the tube, to set up a standing wave of sound in the air-filled top portion of the tube. (That air-filled top portion acts as a tube with one end closed and the other end open.) Take the speed of sound to be 343 m/s....

    1) Imagine you are using a closed end tube with a tuning fork having a frequency of 472 Hz in lab. You notice the second resonance point occurs when the water level is 54.0 cm from the open end of the tube. Ignoring any end correction effect, what is the speed of sound in the lab in this situation?

    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...
