In 1888, German physicist Heinrich Hertz produced and detected electromagnetic waves in his laboratory by using a spark gap attached to an induction coil and a separate spark gap on a receiving antenna. He accomplished his goal of verifying predictions by Scottish physicist James Clerk Maxwell that light and heat are electromagnetic radiations. His discovery made possible the inventions of radio, television, satellite communications, mobile phones, radar and other devices.
