How are microwaves generated
WebMicrowaves are a form of radiofrequency (RF) electromagnetic energy. When this energy comes in contact with food, the absorbed energy causes the water molecules in the food to rotate. This movement causes friction between the molecules and produces a rapid rise in temperature. Microwave energy generated by the magnetron is transferred to the ... Web2 de fev. de 2012 · Microwave plasma oscillates electrons, which in turn produces ions by colliding with gas atoms and molecules.
