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.

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.

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

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.

•One year later, Heinrich Rudolf
Hertz proved Maxwell’s theory
about electromagnetic wave by
found electromagnetic wave itself.

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.
