How Microwaves Cook Food. When you hit the start button it usually takes about 2 seconds to heat up a filament inside the magnetron tube, says Schiffmann. The microwaves are then blasted into the food compartment. The commonly used frequency of microwaves, 2.45 gigahertz, is easily absorbed by water, fat, and sugar.
Microwaves refer to the electromagnetic waves in the frequency range of. 300 to 300,000 mega hertz. Once microwave energy is absorbed, polar. molecules and ions inside the food will rotate or collide according to the. alternating electromagnetic field and heat is subsequently generated for. cooking. The use of microwave oven provides a convenient way to. thaw, cook and reheat foods.
