Answer

E_0 e^{i(kz-\omega t)} \hat{x}$.

Here's the solution to question 4:

a) Derive a relation between the wavevector ( $\vec{K}$ ) and angular frequency ( $\omega$ ) for the electric field to be a solution to the wave-equation:

The electric field is given by $\vec{E}(z, t) = E_0 e^{i(kz-\omega t)} \hat{x}$ . The wave equation (as given in the problem for derivation purposes) is $\nabla^2 \vec{E} - \frac{1}{\epsilon_0 \mu_0} \frac{\partial^2 \vec{E}}{\partial t^2} = 0$ .

Step 1: Calculate the Laplacian of $\vec{E}$ . Since $\vec{E}$ only has an $
