Classic experiment of resonance performed at the beginning of the nineteenth century by the german physicist and musician Ernest Chladni. It's original experiment was to sprinkle sand on a plate as it was set to vibrate with a violin bow. The intention was to visualize and analyze the vibrational behavior of flat surfaces, showing the patterns formed by the nodal lines of stationary sound waves.
Equipment developed for resonance experiments in open tube and closed tube. With it you can determine the speed of sound in air with great accuracy.
Experiments can be performed visually using the cork dust to show nodes and wombs of the standing wave or use the microphone.
With the microphone you can find the nodes and wombs of the standing wave by using the function generator.
Furthermore, by using an oscilloscope, it is possible to visualize the appearance of the standing wave inside the tube, that is captured by the microphone and thereby get a result also more accurate.
Set for study of acoustics and waves. The versatility of the set allows you to perform dozens of experiments with fairly simple assembly. Parts are designed in a modular way, allowing a wide range of studies with a very compact and versatile set.
