In this case $ \omega ^ {2} - \gamma ^ {2} k ^ {4} = 0 $. This relation is called the dispersion relation. There are generalizations to non-linear wave equations, e.g., the KdV-equation, where the dispersion relation also involves the amplitude. Dispersion relations for waves are extensively discussed in .

A general dispersion relation or sum rule for the extinction cross section of such waves is derived from the holomorphic properties of the scattering amplitude in 

A method for approximate determination of dispersion relations and displacement fields associated with elastic waves in long prismatic bars is  a particular focus on how two features of virtual teams, namely frequency of face-to-face meetings and geographical dispersion, moderate that relationship. The dispersion relation for de Broglie waves can be obtained as a function of k by substituting p h/ k into Equation 5.23.

Since ω / k is basically to the (phase) velocity of the wave, the dispersion relation describes the dependence of the phase velocity on the wavelength. The best known example is the dispersion of light by a prism: = (). The dispersion relation has two solutions: ω = +Ω(k) and , corresponding to waves travelling in the positive or negative x–direction. The dispersion relation will in general depend on several other parameters in addition to the wavenumber k. For gravity waves, according to linear theory, these are the acceleration by gravity g and the water depth h. The dispersion relation for these waves is: (dispersion relation) (9) where!0 = p T=m‘.

Dispersion relationship

S Grinshpun  A dispersion relation relates the wavelength or wavenumber of a wave to its frequency. Given the dispersion relation, one can calculate the phase velocity and group velocity of waves in the medium, as a function of frequency. The dispersion relationship (8.137) for linear internal waves with constant buoyancy frequency contains a few genuine surprises that challenge our imaginations and violate the intuition acquired by observing surface or interface waves. One of these surprises involves the phase, c, and group, cg, velocity vectors.

Research of pay dispersion in the Swedish market is even scarcer. Both Heyman (2005) as well as Hibbs and Locking (2000) found a positive relationship between pay dispersion and performance in Swedish companies. Because of the increase of executive compensation and pay dispersion in recent years, we find The relationship between P-wave dispersion and echocardiographic indices of left ventricular function (while controlling for the effect of anaemia) (haematocrit) was examined using the partial correlation analysis. resultsThe mean ages of the patients and controls were 28.27 ± 5.58 (range 18-44) and 28.37 ± 5.91 (range 18-45) years, respectively. Increased P-wave dispersion has been noted in hypertensive patients with diastolic dysfunction when compared with patients without diastolic dysfunction.10 Although some studies have suggested that left atrial diameter is an important predictor of atrial fibrillation, and that P-wave duration is related to left atrial dimension, the present study did not observe any relationship between P-wave The opposite of an inverse relationship is a direct relationship. Two or more physical quantities may have an inverse relationship or a direct relationship.
