  2. Sulfur lamp - Wikipedia

    en.wikipedia.org/wiki/Sulfur_lamp

    Sulfur lamp inside a Faraday cage, which is necessary to prevent microwave radiation leakage from the magnetron which would cause radio interference. The sulfur lamp (also sulphur lamp) is a highly efficient full-spectrum electrodeless lighting system whose light is generated by sulfur plasma that has been excited by microwave radiation.

  3. Microwave oven - Wikipedia

    en.wikipedia.org/wiki/Microwave_oven

    A microwave oven, c. 2005 Simulation of the electric field inside a microwave oven for the first 8 ns of operation. A microwave oven heats food by passing microwave radiation through it. Microwaves are a form of non-ionizing electromagnetic radiation with a frequency in the so-called microwave region (300 MHz to 300 GHz).

  4. SMD LED - Wikipedia

    en.wikipedia.org/wiki/SMD_LED

    Non-SMD types of LED lighting also exist, such as COB (chip on board) and MCOB (multi-COB). Surface-mounted device LED modules are described by the dimensions of the LED package. A single multicolor module may have three individual LEDs within that package, one each of red, green and blue, to allow many colors or shades of white to be selected ...

    Martin's current product line includes the Martin MAC Viper, the LED MAC Quantum series and MAC Aura and the RUSH DJ range, a successor to the Martin Mania range. Another of Martin's current product line is the Era series featuring the era 400 performance, the era 500 hybrid up, the era 600 performance, the era 300 profile and the era 800 ...

  6. Microwave - Wikipedia

    en.wikipedia.org/wiki/Microwave

    A microwave oven passes microwave radiation at a frequency near 2.45 GHz (12 cm) 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 ...

  7. Microwave chemistry - Wikipedia

    en.wikipedia.org/wiki/Microwave_chemistry

    Application of microwave heating to heterogeneous catalysis reactions has not been explored intensively due to presence of metals in supported catalysts and possibility of arcing phenomena in the presence of flammable solvents. However, this scenario becomes unlikely using nanoparticle-sized metal catalysts.

  8. Cosmic microwave background spectral distortions - Wikipedia

    en.wikipedia.org/wiki/Cosmic_microwave...

    CMB spectral distortions are tiny departures of the average cosmic microwave background (CMB) frequency spectrum from the predictions given by a perfect black body.They can be produced by a number of standard and non-standard processes occurring at the early stages of cosmic history, and therefore allow us to probe the standard picture of cosmology.

  9. Aviation obstruction lighting - Wikipedia

    en.wikipedia.org/wiki/Aviation_obstruction_lighting

    Aviation obstruction lighting is used to enhance the visibility of structures or fixed obstacles which may conflict with the safe navigation of aircraft. Obstruction lighting is commonly installed on towers, buildings, and even fences located in areas where aircraft may be operating at low altitudes.
