Interference Sand Table Pattern
Two ripple sources overlapping into moiré bands — wave physics as still geometry.
Drop two stones in a pond and this is the diagram. The crossing wavefronts brighten and cancel in bands the sand holds perfectly still.
Why it fits Drift: Drop two stones in a pond and this is the diagram. The crossing wavefronts brighten and cancel in bands the sand holds perfectly still.
