- A kitchen appliance which utilizes microwaves to heat food. A microwave oven incorporates a magnetron utilized in a continuous-output mode, which radiates microwave energy throughout the oven cavity. This power, which can exceed 1000 watts, causes molecules in the food, especially those of water, to vibrate, thereby producing the heat necessary for thawing and/or cooking. Also called microwave (3), or microwave range (3).
