How are microwaves created
Web3 de mar. de 2024 · Microwaves are also very energy-intensive, so it takes a lot of energy to create microwaves naturally on Earth. The reason scientists believe microwaves in nature is occurring is due to an area on the outskirts of Earth’s atmosphere called the ionosphere. This layer of Earth’s atmosphere is where the sun’s radiation interacts with ... WebMicrowaves bounce around in the chamber and cook food through radiation heating —exciting molecules within an object—by becoming lodged in water, sugars, and fats. Because the microwaves can travel only so far into an object before losing momentum, the outsides of thicker foods become heated by microwaves, and the insides are heated ...
