TITLE
How Radio Waves Work
INTRODUCTION
This paper is about radio waves and the discovery of it. This paper was complete in partial fulfillment of the course requirements of NASC 2100 as assigned by our instructor at Shorter College, Professor Joe B. Campbell.
MATERIALS AND METHODS
I went to the East Marrietta branch library to find the book The Age of Electronic Messages. I searched the Google internet database for How Stuff Works about Radio Spectrum I also researched Wikipedia for detailed information on Heinrich Hertz. I also searched the Galileo search engine, but did find anything that I could use for this paper.
RESULTS AND DISCUSSIONS
Heinrich Hertz was a student of Dr. Herman von Helmholtz. Hertz was fascinated with the meteorology and found himself occupied with the theory of electromagnetic. In 1864, James Maxwell had a theory of electromagnetic waves being transmitted by sparks. In 1886, Heinrich Hertz proved that electricity can be transmitted in electromagnetic waves while at the University of Kiel. Hertz made a simple receiver with loop wire, and at the ends of the loop were small knobs separated by a tiny gap. Then the receiver was placed several yards from the oscillator. When Hertz turned on the oscillator this was the first transmission and reception of electromagnetic waves. Hertz also developed a dipole antenna. This antenna was an element used for transmitting or receiving radio frequency energy. He was known for being the first to broadcast and receive radio waves. His name also became the term used for radio and electrical frequencies: hertz (Hz). A frequency of 1 Hz means there is one cycle or oscillation per second. We now use the terms Kilohertz (kHz), or thousands of cycles per second, megahertz (mHz), or millions of cycles per second, and gigahertz (gHz), or billions of cycles per second all the time.
