What is Marconi’s contribution to science?

Guglielmo Marconi, a famous Italian physicist, invented the wireless telegraph. He is hailed as the ‘father of radio’.

  He began conducting his experiments with radio waves with the aim of utilizing them to produce a useful system of ‘wireless telegraphy’. Radio waves are streams of energy that carry electric signals through the air. Marconi created a telegraph that could send electric signals, using send electric signals, using radio waves.

   The signals travelled through the air, instead of through wires. In 1897, he formed a wireless telegraph business in England. In 1901, Marconi sent radio signals across the Atlantic Ocean for the first time. As a result of his success Marconi was awarded the Nobel Prize for Physics in 1909, along with Karl Ferdinand Braun, ‘in recognition of their contributions to the development of wireless telegraphy’.
