A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to vibrate [2] and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently ...
Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves. Its wavelength ranges from about one meter to one millimeter, corresponding to frequencies between 300 MHz and 300 GHz, broadly construed. [1][2]: 3 [3][4][5][6] A more common definition in radio-frequency engineering ...
In 1947, the first commercially produced microwave oven was about 6 feet tall, weighed about 750 lbs, and cost about $5,000 (equivalent to $68,227 in 2023). In 1967 the first more affordable, $495 (equivalent to $4,523 in 2023), and reasonably sized (counter-top) Radarange brand microwave oven was made available for sale, [ 2 ] produced by ...
An oven is a tool that is used to expose materials to a hot environment. Ovens contain a hollow chamber and provide a means of heating the chamber in a controlled way. [1] In use since antiquity, they have been used to accomplish a wide variety of tasks requiring controlled heating. [2] Because they are used for a variety of purposes, there are ...

The company was founded in 1953 and was named after inventor Charles Litton Sr., who was also an early investor in the company. During the 1960s, the company began acquiring many unrelated ...
Refrigerator, toaster, kettle, microwave, blender. A home appliance, also referred to as a domestic appliance, an electric appliance or a household appliance, [1] is a machine which assists in household functions [2] such as cooking, cleaning and food preservation. The domestic application attached to home appliance is tied to the definition of ...
Microwave chemistry is the science of applying microwave radiation to chemical reactions. [1][2][3][4][5] Microwaves act as high frequency electric fields and will generally heat any material containing mobile electric charges, such as polar molecules in a solvent or conducting ions in a solid. Polar solvents are heated as their component ...
