How+it+works

media type="custom" key="3837609"How it works??? We tend to not care about how the signal works and how the sound gets to our ears. But we care we want to know. A radio starts with a sound that goes into a micro phone, then they amplify the noise and send it through the atmosphere in carrier waves to be picked up by a receiver (antennae). All of this is done at the speed of light! Which almost makes the radio live! Old radios still did pretty much the same thing. When you put the aerial up it gives you more range so you can get stuff from different places. A Tv and radio transmits the same way, Tvs are just the same as radios except more expsensive.
