- Homework Statement
- Prove the invariance of the electromagnetic wave equation by showing that the corresponding differential operator is an invariant.

- Relevant Equations
- d^2/dx^2+d^2/dy^2+d^2/dz^2-1/c^2d^2/dt^2 = d^2/dx^2+d^2/dy^2+d^2/dz^2-1/c^2d^2/dt^2

of course y and z terms are invariant but for the x and t terms I am getting an additional factor of 1/1-v^2/c^2
