Plan view of a walker’s wave field as it passes through a double slit
at the highest memory considered, γ/γF=0.998. We note that, while
the wave field effectively fills the entire bath, the outer boundary does
not alter the drop motion until it approaches within 2-3 λF . Slit width
L = 3.1λF , distance between their centerlines d = 4.21λF , slit breadth
b = 6 mm. Fluid depth over the barriers h1 = 0.42 mm, drop diameter
D = 0.78 ± 0.02 mm, free speed u0 = 11.9 ± 0.2 mm/s. The lid was
removed in order to visualize the wave field.
