   To be pedantic, only through a vacuum...   
   Light, with less penetrating ability due to its smaller wavelength, will be   
   slowed down by constant absorption and re-emission by the medium's   
   molecules. Radio waves will go straight on past.   
      
   Space isn't quite a vacuum, so the speed of light may be slightly lower than   
   the speed of radio waves. Not a factor of 100 though.
