Answer 2

You would need a book to explain it all, but to try and make it very basic, you crate sound into a mike this in turn is ampified and resonates (vibrates) your antenna which makes waves in the ether (air) like dropping a stone in a pool, the waves go out in all directions, if the antenna of a reciever is tuned in ie: the right length, the it vibrates as the waves strick it sending a signal to the speakers, that's how they sent morse code, then with valves, osilators, etc, it progressed from there, untill circuit boards came out and everything went very small.

Answer 3

Basically a signal is generated by one entity at the output end and received, potentially, by many at the receiving end.

But, as others have indicated, this is an answer requiring quite a bit of reading and research. Can't be properly dealt with in YA.

Just enter radio in your favorite search engine and start reading and learning.

Good luck.

Answer 4

Einstein said it was like a long cat.  You pulled his tail in Boston and it meows in Los Angeles.  Only it's done without the cat.    Seriously it's done by intelligent disturbances of magnetic fields surrounding everything.  The disturbance is done electromagnetically and the receiver decodes that disturbance.  Further would take hours and volumes.
