Microwave-oven-information, a microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. this induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.. A microwave oven is an appliance that cooks or warms up food using microwaves produced by an electronic vacuum tube called a magnetron. the magnetron converts electricity to electromagnetic radiation (the microwaves), which is made up of waves of electric and magnetic energy., microwave ovens use radio waves set at a specific frequency — 2,450 megahertz with a power ranging from 500 to 1,100 watts, according to the world health organization (who). food that sits in a....
Microwave oven history this microwave oven history lesson will give you some interesting facts about how the microwave oven came into being. microwave ovens have been a feature of most of our kitchens since the early to mid 1990’s. did you know however that the first microwave ovens were already commercially available way back in 1947?, microwaves facts microwave ovens were invented by accident by an engineer named percy spencer when a chocolate bar in his pocket melted while building magnetrons for radar sets in the 1940s. the microwave, which relies on radio waves to work, was theorized by james maxwell clark in 1864, and tested in 1886 by henrich hertz..
Scientifically speaking, regular microwaves emit waves that bounce around until they come in contact with food, causing water molecules to excite and generate heat, which then cooks the food. in contrast, convection oven technology uses a fan to force air movement and heat up the full interior of the microwave to cook food from the inside out., in a microwave oven, the air in the oven is at room temperature, so there's no way to form a crust. that is why microwavable pastries sometimes come with a little sleeve made out of foil and cardboard. you put the food in the sleeve and then microwave it. the sleeve reacts to microwave energy by becoming very hot..
Microwave ovens are convenient because they cook food much quicker than other methods, and they can be used to defrost frozen food. making delicious and nutritious meals in the microwave isn't quite as simple as it seems, and getting the best results from your food means following a few rules., microwave ovens cook food using waves of energy that are similar to radio waves but shorter. these waves are remarkably selective, primarily affecting water and other molecules that are electrically asymmetrical — one end positively charged and the other negatively charged..
Microwave with advantium® speedcook technology get outstanding, oven-quality results two to eight times faster than a conventional oven with advantium speedcook technology. plus, powerful halogen bulbs eliminate the need to preheat.
