Noun
(physics) the point of maximum displacement in a periodic system
Source: WordNetImpedance mismatches result in standing waves along the transmission line, and SWR is defined as the ratio of the partial standing wave 's amplitude at an antinode (maximum) to the amplitude at a node (minimum) along the line. Source: Internet
For example, in all of the modes analogous to s orbitals (the top row in the animated illustration below), it can be seen that the very center of the drum membrane vibrates most strongly, corresponding to the antinode in all s orbitals in an atom. Source: Internet
None of the other sets of modes in a drum membrane have a central antinode, and in all of them the center of the drum does not move. Source: Internet
This antinode means the electron is most likely to be at the physical position of the nucleus (which it passes straight through without scattering or striking it), since it is moving (on average) most rapidly at that point, giving it maximal momentum. Source: Internet
