What is a microwave oven and how does it work?
A microwave oven is a kitchen appliance that cooks food by using electromagnetic radiation in the microwave frequency range. This technology is based on the principle that water molecules in the food absorb microwave energy, causing them to vibrate rapidly and generate heat. This heat then cooks the food from the inside out, making it a quick and effective method of cooking.
Inside the microwave, a component called a magnetron produces microwaves, which are directed into the cooking chamber. The food is placed on a turntable or a flat surface, where it is exposed evenly to the microwaves. The design of the oven ensures that the microwaves reflect around the interior and penetrate the food thoroughly, creating an efficient cooking process.
