Plane Wave with Vertical Polarization (1)

 
Here was a first-cut 3D drawing of a uniform plane wave.  The red arrows are electric field, the green arrows are magnetic field, and the white arrow is direction of propagation.  (Most of the students didn't like this one.)
 
 

Notes:

  • A very "busy" animation, but at least you can see the traveling wave behavior of the fields in space.
