Hi! I'm Heinrich Hertz,a German physicist.I proved the existence of radio waves in the late 1880s.I showed my experiments that these signals possessed all of the properties of electromagnetic waves.
I 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 my honor.
I used this field theory to assumed that light was an Electromagnetic Wave,and then correctly deduced the finite velocity of light,it was a powerful logical argument of the exixtence of the electromagnetic force field,and that light was a wave like change in the field that propagated with the velocity of light through the other.
Hello,I am James Clerk Maxwell,an English scientist,I developed a scientific theory to explain electromagnetic waves.
Good day everyone!,Im Hans Christian Oersted a Danish physicist and chemist.I discoverd that electric currents create magnetic fields,which was the first connection found between electricity ad magnetism.
I showed th experiment that an electric current flowing through a wire could move a nearby magnet.The discovery of electromagnetism set the stage for the eventual developement of our modern technology-based world.
