The Sine Wave Generator is an excellent tool for generating waves with speakers or wave drivers. It allows the frequency (1-800 Hz) and amplitude of the sine wave to be varied. Students can observe the quantum nature of standing wave patterns as the Sine Wave Generator jumps from one resonant frequency to the next. Both fine and coarse frequency controls are included, as well as a digital display featuring a 0.1 Hz resolution. The generator also features built-in memory that allows it to “learn” new fundamental frequencies for further exploration.
