Dispersion or Spread is the extent to which the observations vary about their mean in a dataset. The quantity that measures a dispersion in a data set is known as measure of dispersion. It is used to check variability/spread of data i.e. to know how much homogenous or heterogeneous the data is. Web30 mrt. 2024 · A dispersion relation tells you how the frequency ω of a wave depends on its wavelength λ --however, it's mathematically better to use the inverse wavelength, or wavenumber k = 2 π / λ when writing equations because the phase velocity is v p h a s e = ω / k and the group velocity is v g r o u p = d ω / d k. These apply to all types of waves. makers cask strength 46
