This comprehensive and economical set is based on a mechanical vibration generator and a sine wave signal generator and includes a support system anda range of accessories. The imprtant basic types of mechanical vibrations and waves can be investigated. Includes demonstrations featuring: transverse standing waves on a vibrating string, Longitudalstanding waves on a helical spring, standing waves on a hoop (model of atomic quantization), resonant vibrations of metal strips, an dresonance patterns on round an dsquare vibrating plates (Chladni plates). Set features a stable and easy to use extruded bench, robust and reliable mechanical generator, amplified sine wave generator with large, 3-digit frequency display, two frequency ranges (1-400Hz x 1Hz and 0.01-4.00kHz x 0.01kHz), and excellent easily visible resluts. The wide range of accessories allows both of the fundamental topics of transverse and longitudinal waves to be demonstrated and enables further investigation of resonance phenomena in various systems from the famous and basic waves on a string to the advanced and complex nodal patters on vibrating plates.
