  2. 2. MICROWAVES PRODUCE HARMFUL RADIOACTIVE RADIATION… <ul><li>THIS IS NOT TRUE! Microwaves used in radar equipment, the telephone, and television and radio communication are in the non-ionizing range of electromagnetic radiation. </li></ul>Gallawa
  3. 3. MICROWAVES ARE… <ul><li>Radio frequencies between one gigahertz and three hundred gigahertz </li></ul>Williams
  4. 4. MICROWAVES ARE… <ul><li>very short waves of electromagnetic energy that travel at the speed of light which is 186,282 miles per second </li></ul>Gallawa
  5. 5. ELECTROMAGNETIC ENERGY <ul><li>They can travel millions of miles through empty space because electromagnetic waves are stored energy in motion </li></ul>Gallawa
  6. 6. PEOPLE USE MICROWAVES FOR… <ul><li>communication because they used very long wave lengths and a low frequency so they will travel a further distance than other and shorter waves </li></ul>Williams
  7. 7. NUMEROUS APPLICATIONS IN THE MILITARY <ul><li>Soldiers now have the ability to communicate to their commanding officers from the battlefield </li></ul>Microwaves
  8. 8. WEAPONS <ul><li>United States Navy is exploring the idea of using High Power Microwave techniques for building an anti-ship missile defense and command control warfare weapon. </li></ul>Microwaves
  9. 9. TELEPHONE COMPANIES <ul><li>had placed towers in specific areas which were about thirty to sixty miles apart and were equipped with antennas, receivers and transmitters </li></ul>Mullen
  10. 10. VACUUM TUBE <ul><li>This allowed us to control the frequencies. Because the frequencies can now be controlled this led to multiple channels, and the commercial and industrial radio to be born. </li></ul>Gallawa
  11. 11. COMMUNITY ANTENNA TELEVISION INDUSTRY <ul><li>Microwaves made it possible for community antenna television systems to operate many hundreds of miles from the actual television stations. This allowed for a larger population of the nation to gain access to television. </li></ul>Mullen
