Answer 1

Back in 1864 the Scottish mathematician James Clerk Maxwell predicted that radio waves could be generated. He wrote down four equations describing them. In the 1880s Heinrich Hertz, a German, became the first person to demonstrate radio waves experimentally. His generator was a spark transmitter; it was an induction coil which produced a high voltage electric spark. His detector was a loop of wire a few metres away with the ends very close together. When the induction coil produced a spark, the radio waves this generated induced an electric current in the loop and a spark jumped across the gap. Twenty years later, Marconi used the same method to send a radio signal from Cornwall and detect it in Newfoundland on the other side of the Atlantic. The only improvements he added were transmitting and receiving aerials. It was about another 15 years before anybody came up with anything better than a spark transmitter.
