  •  James Clerk Maxwell & Heinrich Hertz
  • Who are the different scientist that contributed the theory, Mary?
  • IS THAT SO? CAN YOU WHATS THEIR CONTRIBUTION?
  • SURE, NO PROBLEM!
  • About 150 years ago, James Clerk Maxwell, an English scientist, developed a scientific theory to explain electromagnetic waves. He noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves. 
  • AND ALSO Maxwell discovered that a CHANGING magnetic field will induce a CHANGING electric field and vice-versa.
  • IN OTHER HANDS, Heinrich Hertz, a German physicist, applied Maxwell's theories to the production and reception of radio waves. The unit of frequency of a radio wave -- one cycle per second -- is named the hertz, in honor of Heinrich Hertz.
  • Hertz proved the existence of radio waves in the late 1880s. He used two rods to serve as a receiver and a spark gap as the receiving antennae. Where the waves were picked up, a spark would jump. Hertz showed in his experiments that these signals possessed all of the properties of electromagnetic waves.
