How it works.
The model combines waves from two sources oscillating together. Frequency and source separation change the displayed pattern; the water surface and screen projection show the same model from different viewpoints.
Start with the two sources
Reset to 16 Hz and 5 cm. Locate both sources and compare the water surface with the screen below.
Change frequency
Hold spacing fixed and change frequency. Watch the wavelength readout and the spacing of the displayed wave fronts.
Change source spacing
Hold frequency fixed and move the sources apart. Compare the pattern, then pause to inspect the nodal regions.

About this model
- Two coherent sources; model water depth is fixed at 6 mm.
- This is an illustrative model, not a calibrated laboratory measurement. Water depth and wave amplitude are not adjustable here.
In the full experience, use the frequency and spacing controls, then pause or reset to compare the pattern.
