What is Microwave Oven?

The technology of microwave oven is different from other ovens. In this, Microwave Radiation is used to cook or heat the food. To know about microwave oven in detail, it is necessary to understand microwave radiation first. Microwaves are a form of electromagnetic radiation, in which magnetic energy and electrical energy move together. Microwaves are also used in industries to dry and cure plywood, to make breads and donuts, and even to cook potato chips.

How does Microwave Oven work?

Using a microwave oven, food can be cooked very quickly and efficiently. It transmits the heat directly to the molecules inside the food. Microwave rays heat the food in the same way as the sun’s rays heat our face. Microwave oven is like a sturdy metal box. A microwave generator is installed in it. It is called Magnetron. When you start cooking, the magnetron takes power from the power outlet and turns it into 12cm (4.7inch) long microwaves. Now these microwaves keep reflecting in the metal inside the oven where they are absorbed by the food. The food is placed on a turntable inside the oven for cooking. It rotates slowly so that the microwave rays fall on the food evenly. As soon as the microwaves enter the food, the water molecules present in the food start vibrating rapidly. Due to this heat is generated in them and the food becomes hot.
