| In electronics, an electrode is a conductor used to make contact with a non-metallic part of a circuit |
| Cathode |
| A cathode is an electrode through which (negative) electric current flows out of a polarized electrical device. |
| X-ray |
| An X-ray (or Röntgen ray) is a form of electromagnetic radiation with a wavelength in the range of 10 to 0.01 nanometers. X-rays are a form of ionizing radiation and as such can be dangerous. In many languages it is called Röntgen radiation after one of the first investigators of the X-rays, Wilhelm Conrad Röntgen. |
