Suppose a light pulse is sent out by an observer S in a car moving with velocity v. The light pulse has a velocity c relative to observer S. = It now reads $$\psi_1(x',t') = x'-v\psi_2(x',t').$$ Solving for $\psi_2$ and differentiating produces $${\partial\psi_2\over\partial x'} = \frac1v\left(1-{\partial\psi_1\over\partial x'}\right), v\ne0,$$ but the right-hand side of this also vanishes since $\partial\psi_1/\partial x'=1$. It should always be remembered that the Galilean equations are applicable and physically valid in a Newtonian framework. Galilean Transformation -- from Wolfram MathWorld In physics, a Galilean transformation is used to transform between the coordinates of two reference frames which differ only by constant relative motion within the constructs of Newtonian physics.

Maybe the answer has something to do with the fact that $dx'=dx$ in this Galilean transformation. 0 13. Their conclusion was either, that the ether was dragged along with the earth, or the velocity of light was dependent on the velocity of the source, but these did not jibe with other observations. However, if $t$ changes, $x$ changes. 0 The difference becomes significant when the speed of the bodies is comparable to the speed of light. In special relativity the homogenous and inhomogenous Galilean transformations are, respectively, replaced by the Lorentz transformations and Poincar transformations; conversely, the group contraction in the classical limit c of Poincar transformations yields Galilean transformations. 2 \begin{equation} This proves that the velocity of the wave depends on the direction you are looking at.
