When microwave ovens became popular in the 1970s, they raised the comfort at home to a new level. A conventional food oven heats very slowly, but the functioning of microwave ovens use high power radio waves to cook food. This is the reason why a microwave oven can cook a piece of meat approximately six times faster than a conventional oven. Microwave ovens also save energy, because it can be cooked immediately without waiting for the oven is heated to a high temperature. There are many myths about the functioning of the microwave but the only thing that is true is really birndan spacious facility for a quiet life where food preparation ceases to be something tedious where much time is reversed. Microwave ovens produce electromagnetic radiation of exactly wavelength to excite water molecules.
When water molecules are excited, heated. Since most of our foods contain a good amount of water, it they can heat our food in a selective manner thanks to the warming of the water in the inside of the food. The microwave radiation also pass through the glass and plastic, allowing you to travel through these elements and heat the food inside. However, microwave radiation does not penetrate very deeply in own food, so if you put something in the microwave oven for a short period of time, it is going to be hot on the outside, but still fresh in the Center. Is it dangerous to put metal in the microwave? really turns out to be something inefficient because the robota this material with microwave radiation, does not heat the food and can llerse to fectar the mechanism inside the oven microwave. It should know how to handle the frequencies of waves radiaxcion to make sure that the metal will not affect baked.
Microwave ovens can definitely be harmful if used incorrectly. Den microwave radiation can pass through the plastic and glass, but will reflect on the metal. If it is placed a metal (such as a casserole or a metal fork) object in the microwave oven, it can cause microwave to reflect back the waves to the source that produces them (this is known as magnetron), and may result in considerable damage to the oven. As well as most of the other tools that we use every day, the microwave oven can be a great convenience, but can also be very dangerous when used recklessly. The key is to understand how it works, and make good decisions when use you. Original author and source of the article
