As was shown in figure 1, the locations of the maximum deposition and erosion are fixed relative to the local wave nodes and antinodes.
For sufficiently small wavelengths, nodes and antinodes appear in the maximum amplitude curve.
For near perfect reflection, erosion is zero directly beneath the antinode and attains maxima on both sides of the antinode.
Under a wave antinode where the horizontal orbital velocity is the smallest, the forcing is negative, hence causing erosion and form a bar trough.
Halfway between two nodes there is an antinode, where the two counter-propagating waves "enhance" each other maximally.
If the string is pinched at the antinode of the intended overtone, no higher overtones will sound.
When used to eliminate standing waves, the ferrite sheath current filter must be placed at a current antinode, but not at standing wave nodes.
In organ pipes, an antinode is not formed exactly at the open end.
