Hey guys,
I came across this the other day...
http://electronics.howstuffworks.com/radio1.htm
Could someone please explain how radio waves are produced when you short the leads of the battery with a coin ?
And is the radio wave produced of a certain frequency ( I would imagine that it wouldn't be, because you you would then have to tune to that frequency to hear the crackle)?
and what about the carrier wave and so forth, where does all that come into play by shorting the leads? I understand that an AM signal requires a carrier wave in which the message signal (crackle in this case) is superimposed onto...how does that happen here ?
Thanks
