This is indicated by a finite standing wave ratio ( SWR ), the ratio of the amplitude of the wave at the antinode to the amplitude at the node.
22.
Note that as only one of the fundamental sounds, it has a different volume through different pickups, depending on the proximity of nodes or antinodes to the pickup.
23.
For example, pressing the center of the membrane makes all the modes with m = 0 becoming impracticable, since this point is invariably an antinode for these modes.
24.
From an educational point of view the modes of a two-dimensional object are a convenient way to visually demonstrate the meaning of modes, nodes, antinodes and even quantum numbers.
25.
As a result, the suspended particles inside the channel will be forced toward either the pressure nodes or antinodes, depending on the density and compressibility of the particles and the medium.
26.
The intakes, along with the exhaust, are sonically tuned so that the locations of the pressure antinodes of the Mach disks in the propane stream match the locations of the intake apertures.
27.
:: Assuming we're thinking of the same method, it's only possible to calculate the angle between a certain interference band and the central antinode in an interference pattern.
28.
So there is an amplitude maximum ( antinode ) at the boundary, the first node occurs a quarter wavelength from the end, and the other nodes are at half wavelength intervals from there:
29.
If the sound is of a frequency that produces standing waves, the wavelength will be visible in the series of flames, with the tallest flames occurring at pressure nodes, and the lowest flames occurring at pressure antinodes.
30.
Without measuring the distance along the wall from the antinode and the band, it's not possible to find the wall-to-sensor distance .-- talk ) 08 : 13, 26 August 2008 ( UTC)
