I have no idea really, but the above explanation implies reminds me on the double slit experiments. Also, inference is additive in the amplitude, but phase shifts much smaller than the wavelengths are used in interferometers to measure layer depths. https://en.wikipedia.org/wiki/Double-slit_experiment https://en.wikipedia.org/wiki/Double-slit_experiment https://en.wikipedia.org/wiki/List_of_types_of_interferometers https://en.wikipedia.org/wiki/List_of_types_of_interferomete...
