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.
Microwave uses electromagnetic waves known as microwaves. Those waves have a wavelength equal to the diameter of water molecules. When food is kept inside microwave those waves interact with the water molecules present in food. And make them vibrate vigorously.
