    1. Description:

    A magnetron's job is to generate fairly short radio waves. If you could see them, you could easily measure them with a school ruler. They're usually no shorter than about 1mm (0.04 in; the shortest division on a metric ruler) and no longer than about 30cm (12in; the length of a typical school ruler). The magnetron does its stuff by resonating like a flute when you pump electrical energy into it. But, unlike a flute, it produces electromagnetic waves instead of sound waves so you can't hear the resonant energy its making. (You can't see that energy either, because your eyes aren't sensitive to short-wavelength, microwave radiation).
