I was playing around with some manipulations of maxwell's equations and seeing if I could work out the wave equation for light. I get:
[tex]
(\nabla^2 -{\partial_{ct}}^2) \mathbf{B} = -\mu_0 \nabla \times \mathbf{J}
[/tex]
[tex]
(\nabla^2 -{\partial_{ct}}^2) \mathbf{E} = \nabla \rho/\epsilon_0 + \mu_0 \partial_t \mathbf{J}
[/tex]
I had plenty of opportunities to mix up signs (and added back in some of the constants at the end) so I was wondering if anybody can confirm for me whether I got this (constants and signs on the RHS) correct.
