Transcript

  • 1. MICROWAVES BRIANNA BLAZE
  • 2. MICROWAVES PRODUCE HARMFUL RADIOACTIVE RADIATION…
    • 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.
    Gallawa
  • 3. MICROWAVES ARE…
    • Radio frequencies between one gigahertz and three hundred gigahertz
    Williams
  • 4. MICROWAVES ARE…
    • very short waves of electromagnetic energy that travel at the speed of light which is 186,282 miles per second
    Gallawa
  • 5. ELECTROMAGNETIC ENERGY
    • They can travel millions of miles through empty space because electromagnetic waves are stored energy in motion
    Gallawa
  • 6. PEOPLE USE MICROWAVES FOR…
    • communication because they used very long wave lengths and a low frequency so they will travel a further distance than other and shorter waves
    Williams
  • 7. NUMEROUS APPLICATIONS IN THE MILITARY
    • Soldiers now have the ability to communicate to their commanding officers from the battlefield
    Microwaves
  • 8. WEAPONS
    • 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.
    Microwaves
  • 9. TELEPHONE COMPANIES
    • had placed towers in specific areas which were about thirty to sixty miles apart and were equipped with antennas, receivers and transmitters
    Mullen
  • 10. VACUUM TUBE
    • 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.
    Gallawa
  • 11. COMMUNITY ANTENNA TELEVISION INDUSTRY
    • 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.

  • 12. EVOLUTION OF MICROWAVE TECHNOLOGY
    • microwave oven
    Williams
  • 13. EVOLUTION OF MICROWAVE TECHNOLOGY
    • radars
    Williams
  • 14. EVOLUTION OF MICROWAVE TECHNOLOGY
    • satellites
    Williams
  • 15. EVOLUTION OF MICROWAVE TECHNOLOGY
    • cell phones
    Williams
  • 16. EVOLUTION OF MICROWAVE TECHNOLOGY
    • wireless computer networks
    Williams
  • 17. EVOLUTION OF MICROWAVE TECHNOLOGY
    • Asynchronous Transfer Mode (ATM)
    Williams
  • 18. EVOLUTION OF MICROWAVE TECHNOLOGY
    • Radio telescopes to study microwave emissions from stars, galaxies, and potential leftover energy from the big bang
