Complete Chladni Plate Experiment Kit with Function and Vibration Generators
The Complete Chladni Plate Experiment Kit with Function and Vibration Generators provides a comprehensive approach to educating students about waves and sound. The kit includes two metal Chladni plates, with a vibration generator to excite oscillations and sound waves. The included function generator allows the demonstrator and students to experiment with varying degrees of amplification for greater experiment diversity.
What's Included?
- 1 x Square Chladni Plate
- 1 x Circular Chladni Plate
- 1 x Vibration Generator
- 1 x Vibration Generator Mounting Pin With 4mm Socket
- 1 x Function Generator
- 1 x Power Supply for Function Generator

What Is The Function Of This Experimental Kit?
Chladni plates are designed to demonstrate how sound vibrations travel at different frequencies. The plate itself is covered with a fine, powdery substance, and connected to a function generator and vibration generator. When used together, these generators create oscillating sound waves at varying frequencies.
These sound waves move and create shapes with the substance on the Chladni plate, offering a visual demonstration of how sound travels. This makes it highly suitable for use in science and music classes.
What Are Chladni Plates?
Both a circular and a square Chladni plate is included with this Complete Experiment Kit. When either of the plates are used with the included generators, and fine and dry powdery substance (e.g., sand) can be sprinkled on top of the metal surface to generate acoustically excited figures in the dry particles. This offers a visual example of how sound travels. The patterns produced on each plate-shape will differ.
What Is a Vibration Generator?
The Vibration Generator is designed for generating mechanical waves, enabling the observation and study of the oscillations and resonance in sound. It features a robust plastic housing, with a mounting pin and 4mm socket for securely attaching a Chladni plate. It also features a holder for a standing rod (up to 8mm in diameter) on the rear side of the apparatus for demonstrating standing waves in a coil spring.
What Is A Function Generator?
A function generator is a handy power amplifier tool designed for use in various experiments covering simple harmonic oscillation, AC electricity, and induction. This unit outputs sine-wave, triangular wave, and square wave voltages with adjustable amplitude and frequency. When used with this experimental kit, it's purpose is to power the vibration generator (which will generate mechanical waves from the output of the function generator).
The function generator is designed with various useful features, including an illuminated digital display, protection against voltages and spark discharge, an external sweep function, and retractable feet for easy standing of the device.
