And God said...

grad dot E = rho / epsilon-zero
grad dot B = 0
grad cross E = - del-B/del-t
grad cross B = 1/c-square times del-E/del-t
+ micro-subzero time J
... and there was light!

Similarly, have you noticed that sunsets are usually red but sunrises are yellow? This is because normally we are looking at the sunset thru the heated atmosphere, which looks red. Thus a modification is needed to the wave equations above.


And the three-dimensional standing waves made by any boat on a calm lake are also wave equations, though not of light, but following the same physics. It's all the same physics, the same laws, and the same equations.

We're trying to understand.

Me too.
