2. Microwave oven - Wikipedia

   en.wikipedia.org/wiki/Microwave_oven

   Manufacturer. Various. Available. Globally. 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.

3. Microwave - Wikipedia

   en.wikipedia.org/wiki/Microwave

   Microwave. A telecommunications tower with a variety of dish antennas for microwave relay links on Frazier Peak, Ventura County, California. The apertures of the dishes are covered by plastic sheets (radomes) to keep out moisture. Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves (as originally ...

4. Cavity magnetron - Wikipedia

   en.wikipedia.org/wiki/Cavity_magnetron

   The modern magnetron is a fairly efficient device. In a microwave oven, for instance, a 1.1-kilowatt input will generally create about 700 watts of microwave power, an efficiency of around 65%. (The high-voltage and the properties of the cathode determine the power of a magnetron.)

5. These Microwaves Cost $150 or Less, But They Don’t Look It

   This Black+Decker microwave oven offers decent size and power for under $100, making it one of the best options you can get at this price point. Its interior is 0.7 cubic feet, and its glass ...

6. European Union energy label - Wikipedia

   en.wikipedia.org/wiki/European_Union_energy_label

   A new energy label, introduced in 2010, is based on the energy efficiency index (EEI), and has energy classes in the range A+++ to D. [11] The EEI is a measure of the annual electricity consumption, and includes energy consumed during power-off and standby modes, and the energy consumed in 220 washing cycles.

7. Orders of magnitude (power) - Wikipedia

   tech: power of a microwave oven: 1.366 × 10 3 W astro: power per square meter received from the Sun at the Earth's orbit: 1.5 × 10 3 W tech: legal limit of power output of an amateur radio station in the United States up to 2 × 10 3 W biomed: approximate short-time power output of sprinting professional cyclists and weightlifters doing ...

8. Klystron - Wikipedia

   en.wikipedia.org/wiki/Klystron

   A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, [1] which is used as an amplifier for high radio frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power ...

9. Percy Spencer - Wikipedia

   en.wikipedia.org/wiki/Percy_Spencer

   The result was the egg exploding in the face of one of his co-workers, who was looking in the kettle to observe. Spencer then created the first true microwave oven by attaching a high-density electromagnetic field generator to an enclosed metal box. The magnetron emitted microwaves into the metal box blocking any escape and allowing for ...
