Oven mikrogelombang (English: microwave oven) is a kitchen appliance that uses microwave radiation to cook or heat food. [Edit] How it works
The main part of the oven mikrogelombang general:

    * A magnetron,
    * A magnetron control circuit (usually with a microcontroller),
    * A waveguide, and
    * A cooking space
Mikrogelombang oven works by emitting microwave radiation, usually at a frequency of 2450 MHz (with a wavelength of 12.24 cm), through food. Molecule of water, fat, and sugar in food will absorb energy from the microwaves in a process called dielectric heating. Most molecules are electric dipoles, meaning they have a positive charge on one side and a negative charge on the other, and therefore they will turn on when they try to align themselves with the electric field changes induced by the beam wave micro. This molecular movement creates heat.
Heating by ovens is very effective against water, but not so with the fat, sugar, and ice. Heating mikrogelombang wrong sometimes described as resonance of water molecules, this occurs only at much higher frequencies, at about 10 gigahertz.
