The Vibrations And Waves Set by United Scientific is a demonstration kit that pairs a mechanical vibration generator with an amplified sine wave generator covering 1–400 Hz and 0.01–4.00 kHz. Accessories include circular and square Chladni plates, a helical spring, a wire loop, metal resonance strips, and an elastic cord on an extruded bench. Physics teachers use it to show transverse and longitudinal standing waves and resonance in one setup.
