when we derive the wave equation for a an o0ne dimensional wave moving at constant speed we assume that the wave move losslessly that is a plot of [tex]\psi(x,t)[/tex] with [tex]x[/tex] at any time [tex]t[/tex] is same to the extent that one can be obtained from the other by translation.
similarly what are the assumptions when we get the general three dimensional wave equation
[tex]\Nabla ^{2} \psi=\frac{1}{v^{2}} \frac{\delta^{2} \psi}{\delta t^{2}}[/tex]
