Opinion needed on Physics Lab equipment

  1. Jan 3, 2013 #1
    I need to purchase some resonance tubes for a Sound Speed Experiment in our physics lab. I would like to know if any one here has used any of the following apparatus and your opinions on them. All your input will be valuable in making a decision. My feeling is that the water column might be smoother in operation compared to the others. Thanks for your responses, in advance.

    Simple Resonance Tube Set found at Sargent Welch

    Simple-Form Resonance Tube also found at Sargent Welch

    Resonance tube that use water found at Newegg
