Wave length ranging Frequency ranging
•Wave length ranging of microwave is between 1mm – 1m.
•Frequency ranging of microwave is between 300GHz - 300MHz, •So microwave is called as Super High Frequency (SHF) electromagnetic wave.

Conclusion
How to make mikrowave
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.

James Clerk Maxwell
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
How to make microwave
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.
