This
computer visualization activity is designed to help upper-division undergraduate students visualize electromagentic plane waves.
Students use a computer algebra worksheet to explore the electric and magnetic field vectors of a given electromagnetic plane wave by choosing the wave vector $\vec{k}$ themselves.
The whole class wrap-up discussion summarizes how the electric field, magnetic field and wave vectors are related, allowing students to visualization what is planar about electromagnetic plane waves.
Most representations of plane waves used by professionals do not show all of the aspects of a plane wave. This one does.
