Chladni Plates Kit - WA-9607



In the early nineteenth century, Ernst Chladni added another dimension to wave experiments by sprinkling sand on a thin plate and using a violin bow to induce vibrations. The sand collected along the nodal lines of the wave patterns painted clear and beautiful pictures of the various modes of vibration.

The Chladni Plates Kit and Mechanical Wave Driver (SF-9324) allow continuous vibrations to be produced at measurable frequencies. Students can determine the resonant frequencies of the plates and examine the modes of vibration at any frequency.

The Chladni Plates Kit includes a 24 cm x 24 cm square plate, round plate, 0.8 kg of extra-fine sand and a sand shaker. The round plate can be vibrated about its center or an offset point to investigate both symmetric and asymmetric modes of vibration.


Part of our Yousers channel, this YouTube video was independently created using PASCO equipment to demonstrate resonance wave patterns.  It is a very good demonstration of patterns that can be generated using a Chladni plate, Wave Driver and a Function Generator.

    Mechanical Wave Driver

    While the Chladni plate can be set into vibration manually (using a violin bow for instance) we highly recommend mechanically driving it at various frequencies.

    Required - One of the following

    The Mechanical Wave driver requires a function generator providing up to 1 A to an 8 Ω impedence.  And the Chladni plates operate best with one that provides a wide range of frequencies. Among PASCO products, here are the function generators that can be used.
