What is a microwave oven?
What is a Microwave Oven – A Microwave oven heats food using microwaves, a form of electromagnetic radiation similar to radio waves. A device called a magnetron inside the oven produces microwaves. The microwaves reflect off the metal interior of the oven and cause the water molecules in food to vibrate. This vibration results in friction between molecules, which produces heat that cooks the food.
The microwave oven is a household appliance that has revolutionised modern home kitchens. It is designed and primarily used to quickly heat foods, and is most convenient for otherwise time-consuming tasks such as melting butter or heating water. Unlike traditional ovens, microwaves cook food from the inside rather than from the outside.
