As well, there are other points along the medium that undergo vibrations between a large positive and large negative displacement, and are the points that undergo the maximum displacement during each vibrational cycle of the standing wave and are called antinodes.
32.
This means that the simplest standing wave pattern on the guitar string containing only two nodes and two antinodes, determines what musical note we hear, while the more complex standing wave patterns, the other harmonics, determine how that note sounds.
33.
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.
34.
Standing wave patterns can only be produced within the string of the guitar when it is vibrated at certain frequencies, however there are several frequencies with which the string can be vibrated to produce the different patterns of standing waves, each with a different number of nodes and antinodes.
35.
A closed tube ( also called a " stopped pipe " in the node, or point of no vibration, always appears at the closed end and if the tube is resonating, it will have an antinode, or point greatest vibration at the Phi point ( length ?0.618 ) near the open end.
36.
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.
37.
In this sense, subharmonic is a term created by reflection from the second sense of the term harmonic , which in that sense refers to an instrumental technique for making an instrument s pitch seem higher than normal by eliminating some lower partials by damping the resonator at the antinodes of vibration of those partials ( such as placing a finger lightly on a string at certain locations ).
38.
In order for the acoustic waves to propagate into the microchannel, a coupling gel is used to fill the gap between the tubing and the substrate, as shown in Fig . 15B . Applying an AC signal to the IDTs results in the generation of a SSAW field and thus the creation of a non-uniform pressure field in the fluid with a periodic distribution of pressure nodes and antinodes.
