Microwave ovens are very efficient and quick because they transfer heat energy directly to the molecules or tiny particles inside the food. Microwaves work same as the sun heats our face by radiation.
A microwave almost resembles like the electromagnetic waves that zip through the air from TV and radio transmitters. It’s totally an invisible up-and-down pattern of electricity and magnetism that passes through the air almost at the speed of light.
The microwaves that cook food in the oven are just 12 cm in other words its 5 inches long. Despite oven small size, microwaves carry a huge amount of power.
How microwaves oven works?
- Inside the strong metal box, there is a microwave generator called a magnetron. When you will start cooking, the magnetron takes electricity from the power source and then converts it into high-powered, 12cm (approx. 5 inches) radio waves.
- And then magnetron blasts these waves into the food channel through a route called a waveguide. The food sits on a turntable, spinning slowly round so the microwaves cook it evenly.
- The microwaves bounce back and similarly forth off the reflective metal walls of the food compartment, almost just like light bounces off a shiny surface. When the microwaves reach the food throughout, they don’t simply bounce off. Just like radio waves can pass straight through the walls of our house, similarly, microwaves penetrate inside the food. As they move through it, then they make the molecules inside it vibrate more quickly.
- Vibrating molecules have heat so, the faster the molecules vibrate, the hotter the food becomes. Thus the microwaves pass their energy onto the molecules in the food, rapidly heating it up.
A microwave cooks nourishment much speedier than a traditional broiler since it warms both within and outside of the sustenance a similar time, says Schiffmann. A routine broiler or griddle warms the surface of the nourishment first and the warmth bit by bit moves toward the inside. Since the air inside the microwave broiler is room temperature, sustenances don’t get cocoa or fresh as they would with different types of cooking.
