Web28 de out. de 2014 · 0. Cathode rays are originating from cathode as cathode is negatively charged. These rays then hit the gas sample inside the tube and ionize it. The electrons ejected from the ionisation of the gas travel towards anode. These rays are actually electrons produced from the ionisation of the gas inside the tube. Share. Cathodes are induced to emit electrons by several mechanisms: Thermionic emission: The cathode can be heated. The increased thermal motion of the metal atoms "knocks" electrons out of the surface, an effect called thermionic emission. This technique is used in most vacuum tubes. Ver mais A cathode is the electrode from which a conventional current leaves a polarized electrical device. This definition can be recalled by using the mnemonic CCD for Cathode Current Departs. A conventional current describes … Ver mais The word was coined in 1834 from the Greek κάθοδος (kathodos), 'descent' or 'way down', by William Whewell, who had been consulted by Michael Faraday over some new names needed to complete a paper on the recently discovered process of electrolysis.
