2. [8-pts] Once you've rewritten Maxwell's equations for a vacuum, recall that those equations lead directly to wave solutions. Below is a figurel1 of an electromagnetic wave in a vacuum. Note the geometric relationship between the electric and magnetic components of the wave. Using Maxwell's equations in a vacuum explain why the electric and magnetic field vectors are always at...
