Microwave

  1. 1. By :
  2. 2. Electromagnetic Wave Definition A wave which can travel without medium
  3. 3. Microwave Definition Wave length ranging The inventor of microwave •Wave length ranging of microwave is between 1mm – 1m. How to make mikrowave The application in the daily life Conclusion Frequency ranging •Frequency ranging of microwave is between 300GHz 300MHz, •So microwave is called as Super High Frequency (SHF) electromagnetic wave.
  4. 4. Definition The inventor of microwave How to make mikrowave The application in the daily life Conclusion Microwaves are a form of electromagnetic wave with wavelengths ranging from as long as one meter to as short as one millimeter, or equivalently, with frequencies between 300 MHz (0.3 GHz) and 300 GHz.
  5. 5. Microwave Definition The inventor of microwave How to make microwave The application in the daily life Conclusion James Clerk Maxwell Born : 13 June 1831 Edinburgh, Scotland Died : 5 November 1879 National : Scottish Citizen : British In the 15th years old, he was able to present scientific paper work. Maxwell considered the greatest the teoritical physics in the entire period between Newton and Einstein. Maxwel is a scientist who has been tracing the link between symptoms of electricity and magnecity based on the knowledge that already exists at the time
  6. 6. Microwave Definition The inventor of microwave How to make microwave The application in the daily life Conclusion In 1864, he proved that electromagnetic waves are a combination of oscillating electric and magnetic fields. Maxwell found that light is a form of electromagnetic radiation. He also opened the understanding of the motion of the gas, by showing that the rate of the molecules in the gas depends on the temperature, respectively.
  7. 7. Microwave Definition The inventor of microwave •One year later, Heinrich Rudolf Hertz proved Maxwell’s theory about electromagnetic wave by found electromagnetic wave itself. How to make microwave The application in the daily life Conclusion Albert Walace Hull invented magnetron as transmitter of electromagnetic wave
  8. 8. Microwave Definition The inventor of microwave How to make microwave The application in the daily life Conclusion The microwave radiation of microwave oven and some radar applications is produced by a device called a magnetron
  9. 9. Microwave Definition The inventor of microwave How to make microwave The application in the daily life Conclusion
  10. 10. Definition The inventor of microwave GLOBAL POSITIONING SYSTEM How to make microwave RADAR (RADIO DETECTION AND RANGING) The application in the daily life Conclusion MICROWAVE OVEN
  11. 11. Microwave Oven Waveguide Timer & controler c Magnetron Blower motor Food Chamber Transformer Capacitor
  12. 12. Microwave Definition The inventor of microwave How to make microwave The application in the daily life Conclusion • Microwave is an electromagnetic wave which length of wave is between 1mm – 1m, and wave frequency is between 300MHz300GHz • The invention of microwave is based on the inventor of electromagnetic wave, he is James Clerk Maxwell. • Application of microwave in daily life can be found in GPS, RADAR, and Microwave Oven •Microwave radiation can be produce from a component names magnetron • The important thing in microwave oven are magnetron, waveguide and strirer.
