  1. Kundt`s Tube TMF Gymnasium Elišky Krásnohorské

  2. Scheme of the experiment

  3. Primary structure • if Kundt`s tube is tuned, in tube rises standing wave (primary at frequency of sound generator)

  4. Secondary structure • if proportion of length of tube and radius of tube is small, secondary standing wave rises on higher harmonic in tube

  5. Properties of the second structure • the distance beetwen minum and maximum is fundamentally smaller then in primary structure • it isn`t stable – unideal bounce waves on a tube bottom causes a wave motion of secondary structure • it is stronger then primary structure • it is sensitive on tuning the Kundt`s tube • it takes cca 2 - 4 mm in our measurement

  6. Foto of the secondary structure
