Electromagnetic wave complex wave function

Click For Summary
SUMMARY

The discussion centers on verifying the complex wave function of an electromagnetic (EM) wave represented as \(\vec{E}(x,y,z,t) = \vec{E}_0 e^{i(kz - \omega t + \delta)}\). Participants suggest substituting this function into the wave equation \(\nabla^2 \vec{E} = \frac{1}{c^2} \frac{\partial^2 E}{\partial t^2}\) to check for equality. This method is a standard approach in validating wave functions against the wave equation. The conversation highlights the importance of mathematical verification in electromagnetic theory.

Hello!
I am not quite sure how do i verify the complex wave function of EM wave

\vec{E}(x,y,z,t)= \vec{E}0ei(kz-\omegat+\delta)

is a function of the wave equation

\nabla2\vec{E}=\frac{1}{c^2}\frac{∂^2E}{∂t^2}

Have you tried simply plugging it in and seeing if the two sides are equal?

oops my brain must have stopped working... Thanks a lot anyway :)
