Do you know what "nodes" and "antinodes" are in standing waves?

Yes I know that , I am reading about pseudopotentials and I had faced that ( nodless wavefunctions) but I couldn't imagine how they are?!

Note that in the context of pseudopotentials "nodeless" means "without /radial/ nodes" (in the one-particle basis functions; and actually, not even that, only the nodes corresponding the the electrons which are actually absorbed in the ECP are removed). The wave function still maintains all the angular nodes which are resulting from the spherical harmonic perfactors of the atomic wave functions.
