How does a microwave oven work?

Indeed, sir. A microwave oven works by using microwaves, which are a form of electromagnetic radiation. These microwaves are generated by a component inside the oven called a magnetron. When the oven is turned on, the magnetron produces microwaves that travel through a waveguide and into the cooking chamber. These microwaves penetrate the food and cause the water molecules within it to vibrate rapidly. This vibration generates heat through a process known as dielectric heating, which warms the food from the inside out, often more quickly than traditional methods of heating.
