When you open and close a microwave, the following typically occurs:
Opening the Microwave: When you open the microwave door, the internal light usually turns on. This feature is designed to provide visibility inside the microwave, allowing you to monitor your food without exposing yourself to the microwave's active energy.
Interrupting the Operation: Opening the microwave door interrupts the operation of the microwave. Most microwaves are designed with a safety feature that automatically pauses or stops the microwave's heating process when the door is opened. This ensures that the microwave doesn't continue emitting microwaves while the door is open, preventing potential harm.
Stopping the Emission of Microwaves: When you close the microwave door, the latch mechanism ensures that the door is securely shut. This action completes the electrical circuit and activates safety interlocks, allowing the microwave to function properly. Once closed, the microwave can generate and contain microwaves within its cooking chamber.
It's important to note that while microwaves are generally safe to use, proper caution should be exercised. Always follow the manufacturer's instructions and avoid putting objects or materials in the microwave that are not intended for microwave use.
