How Does a Microwave Oven Work?
So how does a microwave oven work? Microwave ovens produce microwave energy (or radio waves), which heats and cooks food. The frequency of the radio wave is about 2,500 megahertz.
In this frequency range, radio waves are absorbed by water, fats and sugars and converted into atomic motion, or heat. They also are not absorbed by most plastic, glass and ceramics.
