Referring to following link about Solar Radio Flux, I would like to know more about Solar Radio Flux, is Solar Radio Flux different from Electric Flux? What is the major difference in term of properties of their fluxs? Does anyone have any suggested materials on what Solar Radio Flux is about? Thanks in advance for any suggestions http://www.spaceweather.ca/sx-4-eng.php Electric flux is the flux of the electric field. Electric flux is proportional to the number of electric field lines going through a virtual surface.
