section::::microwave uses.:heating and power application.





























a microwave oven passes microwave radiation at a frequency near  through food, causing dielectric heating primarily by absorption of the energy in water. microwave ovens became common kitchen appliances in western countries in the late 1970s, following the development of less expensive cavity magnetrons. water in the liquid state possesses many molecular interactions that broaden the absorption peak. in the vapor phase, isolated water molecules absorb at around 22 ghz, almost ten times the frequency of the microwave oven.





























microwave heating is used in industrial processes for drying and curing products.
