I've been following the Tired Light thread in ATM, but don't want to side-track that discussion.
Just some questions about photons, in regards to frequency and energy. For starters, how accurate is this visualization:
1) Is the magnetic field always at a right angle to the electric field?
2) Do the fields rotate along the axis of travel, or are the arrows just representing oscillations in strength of these fields?
Obviously my knowlege is limited, so if the arrows are actually representing the orientation of fields; Aren't these fields a "figure 8" shape? So is there an implied field in the opposite dirrection of the arrows as well?
I know I get myself in trouble trying to physically visualize these things (photons), just trying to grasp it.
