Hello so my doubt is when i are teaching about eletromagnétic filds the frist time a do a representatios is of a full field i Draw the two waves, ume perpendicular to another, and istill i know that's not the best representatios because i should have to rolate the wave while a draw.
Later in the same Class i stop drawing the full eletromagnétic field and it's became a simple wave, but iknow that's when i do this some of the informations is lost and i never could explain to the studentes why i do this, i just do and i know i cam from the textsbooks. So here's my doubt who do i explain to them that's is reliable do this change in the way a represents the eletromagnétic field, i wold really apreciate if some on has a demostration to this ou a textbook to recomendate.
Sorry for my bad english I'm not native in english.
