Working of microwave oven
The working of a microwave oven is as follows:
- Microwave oven is made up of aluminium metal box which cannot pass the radiation and uses magnetron, a microwave generator. When you switch on microwave oven for cooking the food, the magnetron receives electricity from the power outlet and converts it into high-powered radio waves.
- The microwave oven has a waveguide, turntable and a timer switch. When the food enters inside the chamber and the timer is switched on, it sends a command to the magnetron for sending microwaves to the turntable to start rotating. The microwaves heat food which has water molecules
- When the oven is on, it sends microwaves which touch the water molecules
- After this, the water molecules start vibrating at a very high speed and produce heat. The turntable rotates and food is heated calmly.
