Kund’s Apparatus

This apparatus is used to reproduce Kundt’s experiments to study wave motion inside a tube by using sound and by creating ‘standing waves’. The apparatus includes: The transparent resonance tube, 850mm long with metric scale, 2x side holes and sliding shutters, an adjustable piston, a miniature microphone which can be passed up the tube,  a mini-speaker that fits to one end of the tube and produces the sound waves, a driver to Interface the speaker to an amplifier or oscilloscope and an instruction booklet. Only a Signal Generator is required to run the equipment.  An oscilloscope is ideal to determine the maximum and minimum sound levels although a normal amplifier will suffice.
