The difference between the interface shown here where 
and the interface of the standing waves shown in, for example
figure 7-3,
where 
can be seen. Here there is a definite region around
the interface where there is a mixture of the two fluids. This can be see
in figures 8-1 - 8-10 as the grey region
around the interface. This region is not there in figure 7-3
where the interface is much sharper.
