British  

noun

1. physics the relationship between the angular frequency (ω;) of a wave and the magnitude of its wave vector ( k ). Thus the wave's speed is ω/ k

Example Sentences

Kiladis and a colleague later confirmed another of Matsuno’s predictions when they related the length of a Kelvin wave to the frequency of its wiggles — a characteristic known as a dispersion relation — and found that it matched Matsuno’s equations.

From Scientific American

“The fact that this event is twice as far as the previous two gives us a longer baseline to test the dispersion relation, and as a result we now have a limit on the mass of the graviton that is 30 percent tighter than the one we previously set. One could say we are putting general relativity to a tighter and tighter test—it is still holding, but with more signals we may find something that does not quite agree.”
