This fact will be made in the form of coupling, using for it the Cauchy-Riemann conditions for quaternionic functions [#!BorgesZeMarcio!#], through certain Laplace's equation in [#!MaraoBorgesLP!#]. The coupling will relate those functions that determine the wave as well as their respective propagation speeds.263-271porcoupling, coupling wave equations in three dimensional spaceArtigo10.12732/ijpam.v97i3.1Acesso abertoISSN0131-8080-2014-97-03-263-271.pdf7955413331293674
