Data sheet Kundt's tube with analog output


The apparatus is made up of a tube mounted on holder and equipped with a loudspeaker at one end and a removable stopper at the other end. The loudspeaker is supplied with a function generator (not supplied)
enabling you to vary the soundwave's frequency.The amplitude of the sound signal is picked up by an electret-foil microphone, mounted on a mobile rod inside the tube. The displacement is carried out thanks to a turn

Recordings of the displacement and the received signal are made with a computer from any Computer-Assisted Experiment system. An oscilloscope can also be used to display the received signal.
