So in university lectures about the Maxwell's equations and electrodynamics, it's quite common to start
with electrostatic and Magneto's tactics.
However, here for this course, I want to go a bit of a different route, and I want to start with
electromagnetic waves.
This is because I want you to understand what light is and why light behaves like wave.
And I think it's really fascinating that we can derive this from the Maxwell's equations.
However, for this we need to consider a special case, and this is the electromagnetic fields in vacuum.
And what this means, we have to set the charged density roll at the current density to zero.
And this is then, so to say, a special version of our Maxwell's equations.
So let's go ahead and do it.
