$\Large\bold\star\underline{\underline\textbf{Microwave\:}}$

→ Micro waves are radio waves of wavelength 1 mm to 0.3 m. These are produced by oscillating electron in a cavity.

→ Microwaves are used in RADAR.

$\Large\bold\star\underline{\underline\textbf{Microvave oven\:}}$

→ The frequency of the microwaves is so chosen that it matches with the resonant frequency of the water molecules.

→ So the energy of the waves is transferred
to the kinetic energy of the water molecules. This energy therefore, increases the temperature of any food containing water.

→ That's why we use Microwave in cooking.

$\Large\bold\star\underline{\underline\textbf{Properties\:}}$


→ Microwaves are e.m. waves of frequency range 1 GHz to 300 GHz.

→ They are produced by special vaccum tube
(Klystrons, magnetrons etc.)
