(1) However, keep in mind that the third transverse mode also has an antinode at the center of the bar.(2) A region where the variation of a quantity has a relative maximum is called an antinode of that quantity.(3) Very similar to a coffee cup, whose nodes and antinodes are determined by the location of the handle.(4) As the speaker volume increases, the difference between nodes and antinodes becomes easier to hear.(5) If two of the three indices are zero, then the pressure antinodes of the associated mode form planes.
