What is the microoven working principle??

The working principle of a microwave oven is based on the concept of electromagnetic radiation. The oven generates microwaves, which are a form of electromagnetic waves, using a magnetron tube. These microwaves are then directed into the cooking chamber.

When the microwave oven is turned on, the microwaves are emitted and absorbed by the food placed inside the cooking chamber. The microwaves have a specific frequency that causes the water molecules in the food to vibrate rapidly. This vibration generates heat, which cooks the food.

The microwaves are reflected by the metal walls of the cooking chamber, ensuring that they are contained within the oven. The rotating turntable inside the oven helps to distribute the microwaves evenly, ensuring uniform cooking.

The oven also includes a control panel that allows the user to set the desired cooking time and power level. The control panel sends signals to the magnetron tube, regulating the emission of microwaves.

It is important to note that microwave ovens are designed to heat food and not the cooking container itself. The microwaves are absorbed by the food, while the container remains relatively cool.
