The Italian inventor Guglielmo Marconi was a pioneer of long distance radio reansmission between ships at sea and between continents. Having read about German Scientist Heinrich Hertz's work in producing electric waves, Marconi invented the antenna and improved his receivers in sending radio wave upto 2.5 Km.
He increased the range of transmissions upto 15 K.m.
He was awarded Noble Prize for Physics in 1909.
Is this possible? Can you find what the reason for it? I know this is helding with the chemiacal reactions and when change different colours.
He is in the Air He is in the air. Can you belive it? But must belive it.
