In short, microwave ovens are kitchen appliances which are used to cook or reheat food by emitting microwaves. Microwaves are a form of electromagnetic radiation and are on the low energy end of the energy spectrum, second to radio waves. The waves are generated by something called a magnetron – something found within every microwave oven.
Magnetrons produce an electromagnetic field with a microwave frequency of approximately 2,450 megaHertz (MGz), which is the equivalent to 2.4 gigaHertz (GHz). Microwaves produced within the microwave oven cause dialectric heating – they bounce around the inside of the oven and are absorbed by whatever is placed in the oven.
In order for something to heat in a microwave oven, water must be present within the substance. If water is not present, heating will not occur and it would remain cool. The reason for this is that water molecules within the food vibrate at incredible speeds, creating molecular friction which is responsible for the heating of the food. The structure of the water molecules are torn apart and vigorously deformed. This is much different than any other method of cooking, as other methods such as convection ovens heat up food by transferring heat convectionally from the outside inward.
