We all know the explanation videos and other material using the water waves analogy to illustrate the propagation of electrons or photons and the interference patterns measured in the the single-slit and double-slits experiments.
Being just an analogy it misses for sure many attributes by which light/electron waves differ from water waves.
BUT: If limited only to use water-waves analogy would it be possible to simulate the impact of the observer/detector in the experiments by means of water waves (yes, i'm smiling my self at this a little ;)
What would be the properties of such a detector-by-means-of-waves needed to simulate the collapse of the interference pattern, for example?
In other words is it possible to rebuild the double-slit experiment with such a water-waves setup and with same known results?
How about in theory? What ("strange") requirements are there?
For starters maybe let's drop the switching the slit-result and let's assume when the observer is turned on the water wave shows to be originating always from the same slit...
At what earliest point does this "model" break? How?
