Homework Equations
The Attempt at a Solution
Hi. In problem 2a I was supposed to find a wave equation, however while digging around in maxwell's equations, I found this result:

which effectively implies that ##\nabla^2 \vec{E} = 0## if you insert it into the wave equation they want me to find (look in problem 2a to see what I mean), which obviously can't be right.
But where is the fault in my derivation?
