Hi guys, The other day I found myself asking the question below and couldn't quite manage to re-align my own personal experience with E&M theory. I am sure it will just be a gap in my knowledge base of E&M. The Question: If you are contained within a metal mesh cage which acts as a Faraday cage why can you still see out beyond the cage? Surely if a Faraday cage shields the interior from external electromagnetic radiation you should not be able to see out beyond the cage as no 'external' light enters the cage and therefore your eyes. Any help would be much appreciated.
