A description of the vertical structure and the phase speed of long linear internal waves c can be found (in the Boussinesq approximation) from the following Sturm-Liouville problem:
On the other hand, the wavelength can also be 'estimated' from the phase speed [c.sub.p] of the same wave if we assume that the short wave satisfies the linear dispersion relation
where A is the area of impact, K is an empirical constant between 3 and 10, [rho] is the water density and C is the wave phase speed. For the southeast arm of the swastika this is
Figure 2 infers that the phase speed of both (III and IV) modes including and excluding QE increases with increasing carrier drift in terms of [E.sub.0].
The initial portion of the graph (of the multivalued function) showing the variation of the normalised phase speed [[upsilon].sub.p]/c with respect to the normalised frequency [k.sub.0a] for the dielectric loaded tape helix corresponding to 0 < [k.sub.0a] < 1.3 is plotted in Fig.
Thus, if there exist coastal trapped waves, their wavelength, period and other parameters like phase speed are determined by dispersion relations (7) and (8).

Cherenkov radiation occurs when electrons move in a medium with a speed greater than the phase speed of electromagnetic waves in the medium.
A pair of hydrophones or transducers is used to transmit and receive a series of short monochromatic bursts of varying frequencies from which the attenuation and phase speed in the bubbly liquid are determined.
Structure change in the process of a pulling should obviously lead to some mismatch of phase speeds of waves interacting in PPLN, to compensation of the induced wave unbalancing (at the constant period of a domain grid), and as a result of temperature influence to the leveling of own crystal matrix absorption.
