A microwave oven has become a major part of every household these days. It is one of the most amazing wonders of the modern kitchen. This can help you to get the best options for heating food as well as taking advantage of the best of technology. A microwave oven works by emitting radio waves that are, on average, 2,500 megahertz. These waves are absorbed by compounds such as water, sugar and fat within microwaved foods. The microwaves cause each molecule to move rapidly and result in the food becoming hotter. Each type of material placed into the microwave reacts differently, which is why some bowls and plates become hotter than others. Furthermore, metal reflects microwaves, which is why it is advised never to use it when microwaving to avoid damaging the oven.
