Can someone explain radio waves to me please?
What is this stuff? I know you can put a pulse to an antenna and some other antenna will pick it up but how does it work?
Do electrons push against other electrons like the way water pushes against water if you drop a pebble in a pond? If yes why does it pass through vacuum? Why do some radio frequencies travel along the earths surface?
Is this some quantum field vodoo?
Does anybody really know?
