Microwaves are electromagnetic waves with wavelengths between 1 mm and 1 m, or frequencies between 300 MHz and 300 GHz. They were first theorized by James Clerk Maxwell in 1864. Later, scientists like Heinrich Hertz and Albert Hull helped develop practical applications of microwaves such as radar and microwave ovens. Today, microwaves are used widely in technologies like GPS and in household appliances like microwave ovens, which use a magnetron to generate microwave radiation and heat food efficiently.

Frequency ranging
•Frequency ranging
of microwave is
between 300GHz 300MHz,
•So microwave is
called as Super High

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.

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.
