The science of microwave ovens

The first microwave oven radar built in 186 was 8 feet 11 inches high and weighed 20 kg. It consumes three kilowatts of power. For the first time it was N.S. Placed for tourists in the sauna ship. Then came the low power consumption of small microwave ovens after 190. After 190, various companies in Japan, the United States, and other countries built a variety of microwave ovens. After 18, its sales began to grow. The name microwave oven also came from that period.

A microwave oven turns electricity into a microwave with a device called a magnetone and throws it over food. Microwave ovens emit 12 AA waves of 7.5 GHz like normal radio frequencies. These gloves are non-ionizing. Water and fats in food which have molecules of many substances have electric charge. The microwave causes the molecule to rotate and release energy to generate heat. This action starts from the middle of the food and finally the surface heats up. This effect of the microwave is greatest on water. Large industrial microwave ovens can also boil water.

The frequency of radiation used in microwave ovens is the approved frequency used in industrial scientific and medical (ISN). In addition, three other frequencies have been approved for the oven. Manufacturers stick to this standard.

The door of the microwave oven is made of glass. But behind it is a micro wire mesh. In fact, this cooking chamber is a kind of carade cage that does not allow the microwave to come out.
