Wave equation in conductor

    1. The problem statement, all variables and given/known data
    problem 2a)

    2. Relevant equations

    3. 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?

    Ahh, but of course, the charge density is zero in an ideal conductor, is it not? Then what I get out will be nonsense because of that?
