He disconnected one of the room's tube-lights and contacted with the cathode.
The cathode is preferably formed of the same metal which is to be obtained.
The tube is then exhausted until the cathode rays strike against the window.
Waving away that orange gas, he reached for the cathode and held it up.
Next this we have a luminous position called the “negative glow” or the “third cathode layer.”
This is melted in an iron pot which also serves as the cathode in the electrolysis.
The rays start from the cathode A, and pass through a slit in a solid brass rod B fitting tightly into the neck of the tube.
He applied the current, moving the anode and the cathode slowly.
Unlike the cathode rays, they were not deflected by magnets; and neither did they seem to be reflected or refracted similarly.
These rays are called cathode rays because they come from the cathode of the tube.
1834, from Latinized form of Greek kathodos "a way down," from kata- "down" (see cata-) + hodos "way" (see cede). Proposed by the Rev. William Whewell (1794-1866), English polymath, and published by English chemist and physicist Michael Faraday (1791-1867). So called from the path the electric current was supposed to take. Related: Cathodic; cathodal. Cathode ray first attested 1880, but the phenomenon known from 1859; cathode ray tube is from 1905.
