In a microwave oven, you can cook a hamburger in only four minutes. Conventional ovens cook food by heating air which, in turn, heats the food. Microwave cooking is direct. It cooks by creating heat inside the food. Microwaves are pulses of electromagnetic energy which are beamed into food by an electronic tube. As microwaves pass through food, tiny molecules of moisture in the food rub against each other, causing friction, This creates heat - the heat which cooks the food. Rub your hands together quickly, and you'll feel the same "friction heat "
