Microwaves are electromagnetic waves with wavelengths between 1 mm and 1 m, or frequencies between 300 MHz and 300 GHz. James Clerk Maxwell first theorized electromagnetic waves in 1864 and proved that light is a form of electromagnetic radiation. Later, others like Heinrich Hertz and Albert Walace Hull helped develop microwave technology. Microwaves are used for applications like GPS, radar, and microwave ovens. Microwave ovens use a magnetron to generate microwaves that are guided into a food chamber using a waveguide and stirred using a turntable.

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.

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
The Bibliograpy
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.
