Kundt's Tube

  1. Nov 29, 2012 #1
    1. The problem statement, all variables and given/known data

    Kundt's Tube.

    First of all, i used a aluminum rod.

    Then i rubbed it to cause vibration .

    2. Relevant equations
    a)How can i change the frequency of the sound produced in tube.

    b)What is the difference of rubbing the metal with more pressure?

    3. The attempt at a solution

    Changing the material of the rod. (I think that is the only way to change the frequency produced by sound in the interior of the tube, because :

    vsound/λsound = v(material of the rod)/λmaterial of the rod = frequency

    [itex]\frac{vgas}{λgas}[/itex] = [itex]\frac{v(material of the rod)}{λmaterial of the rod}[/itex] = frequency


    The intensity(amplitude) of the sound. When i applied more pressure rubbing the rod, a louder sound was produced.

    Is it correct??

    Help is always appreciated.
