For me personally, this was a real eye-opener. Now I not only understand where the standing waves come from, but that the nodes and anti-nodes map to physical locations on a line that are ...

Standing wave patterns are characterized by certain points that undergo no vertical displacement (nodes). Fluid moves horizontally around the nodes, and midway between them are antinodes ...

This method relies on something called tilted-angle standing surface sound ... which convert power into sound waves. A series of pressure nodes and antinodes are established in the microfluidic ...
