Oceanic wave speeds are dispersive and vary unlike sound waves
the verdict
SUPPORTED
the evidence backs this
confidence 82/100
Oceanic surface and internal gravity waves exhibit dispersion, meaning their phase and group speeds vary with frequency or wavelength, distinguishing them from simple non-dispersive acoustic wave propagation in certain media.
