If the double slit were performed underwater?

I know that photons interact weakly with air molecules which is why we have the interference pattern, and I know they interact strongly with say mud so there would be no pattern in a mud pit, though I am not sure if in a mud pit there would be any kind of light that reaches the screen at all. Anyways I digress do photons interact strongly with water cancelling out the interference pattern thus giving us a regular particle pattern instead of a wave interaction? Also are there any other substances where photons interact strongly where you still see a pattern of light but without the interference pattern? Thanks for your time.

I don't think your premise is right. You can interfere light in glass. Underwater would be a bit messy, but I don't see why it wouldn't work - apart from high voltage issues.
 
Ok but are there any substances where photons interact strongly where you still see a pattern of light on the screen that is not the interference pattern?
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
