   I didn't quite understand your answer. lol   
      
   In any case, I clarify my question further with this other animation   
   https://www.geogebra.org/m/ar3dqcwk   
      
   There is a standing electromagnetic wave in a carousel that rotates   
   360=B0 in 2 time.   
      
   It works exactly like a light clock.   
      
   In the terrain reference, is the time of one complete rotation the same   
   or is it more or less?
