2. 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. 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 ...

   en.wikipedia.org/wiki/Electromagnetic_spectrum

   Microwaves are the main wavelengths used in radar, and are used for satellite communication, and wireless networking technologies such as Wi-Fi. The copper cables ( transmission lines ) which are used to carry lower-frequency radio waves to antennas have excessive power losses at microwave frequencies, and metal pipes called waveguides are used ...
