There is a dedicated forum for optical photon questions, but ok....
Your code is hard to read, but I see that you:
> G4OpticalSurface("WaterSurface"); > OpWaterSurface->SetType(dielectric_dielectric); > OpWaterSurface->SetFinish(ground); > OpWaterSurface->SetModel(unified);
Just don't define a G4LogicalBorderSurface between waterTank_phys and expHall_phys and you will get your expected theoretical refraction angle. Or require:
What you have done is ask G4 to simulate a ground/rough surface without specifying how rought the surface is.
