- What is the minimal thickness of dark wet spots on drying dishes?
A common observation when doing the dishes is that the wet spots on a drying dish are darker than the dry spots, especially if the dish is held in such a way that it reflects the light of the sky. Evidently the total reflection coefficient is reduced by the water film. The border between dark and bright is acute. My question is, at what thickess does the wet film stop being dark, would a thickness of a single molecule still be dark?
