Also, these can create fluorescence, mechanical effects, and more. Since scientists knew it was difficult to deflect electromagnetic waves with an electric field, this was evidence that the beams were made up of particles. This debate between them was resolved when an electric field was used to deflect the rays by J. Also, Crookes insisted it was a particle, while Hertz maintained it as a wave. These conflicting properties have caused disruptions when trying to classify it either as a particle or wave. Ernest Rutherford has demonstrated that the rays could pass through the thin metal foils, the behaviour expected of a particle. Like a wave, the cathode rays travel in straight lines and form a shadow when obstructed by the objects. This particular effect, when coupled with the controlled deflection of a cathode ray either by a magnetic or electric field, the cathode-ray oscilloscope (rather than the cathode-ray tube CRT) is used to track the values and changes of an alternating current or voltage, as well as the image tube used in radar and television. When cathode rays collide with particular molecules used to cover a cathode plate, the molecules (and thus the screen) emit light. X-rays or a very high temperature are created by cathode rays centred on a hard target (anticathode) on a small object in a vacuum (cathode-ray furnace). Send us feedback.A cathode ray is defined as a stream of electrons leaving the negative electrode (or cathode) in a discharge tube that contains gas at low pressure or the electrons emitted by the heated filament in certain electron tubes. These example sentences are selected automatically from various online news sources to reflect current usage of the word 'cathode-ray tube.'

Peter Ford, The Christian Science Monitor, 9 July 2018 The console also offers three display choices: the original 4:3 aspect ratio of the games, a CRT filter that replicates the same blurry look of cathode-ray tube TVs, and a Pixel Perfect mode that makes the games look crisp and clean. 2018 There is mercury in liquid-crystal display screens, lead in cathode-ray tubes, cadmium in semiconductors and batteries, and ozone layer-destroying chlorofluorocarbons in old refrigerators, for example. The Economist, 8 June 2019 When first built in 1965, the consoles had era-appropriate cathode-ray tube monitors. 2020 The idea of a big screen with a fixed connection will be as alien to the second half as landlines and cathode-ray tubes are to today’s youngsters. Kevin Dayhoff, /maryland/carroll, 9 Oct. 2021 Seven years later, Boris Rosing first transmitted silhouetted images of geometric shapes, using a cathode-ray tube receiver. Noah Wardrip-fruin, The Conversation, 29 Nov. Carina Woudenberg, Discover Magazine, Douglas created a game of tic-tac-toe, which was also displayed on a cathode-ray tube, for the University of Cambridge EDSAC computer. Recent Examples on the Web For example batteries need to be removed from cellphones and older, cathode-ray tube television sets require special handling due to their lead content.
