Cathode Ray Experiment by JJ.Thomson (CRT)
A cathode-ray tube (CRT) is a vacuum tube in which an electron beam, deflected by applied electric or magnetic fields, produces a trace on a fluorescent screen. The function of the cathode ray tube is to convert an electrical signal into a visual display. Cathode rays or streams of electron particles are quite easy to produce, electrons orbit ...
Discovery of the electron and nucleus (article)
Thomson also placed two magnets on either side of the tube, and observed that this magnetic field also deflected the cathode ray. The results of these experiments helped Thomson determine the mass-to-charge ratio of the cathode ray particles, which led to a fascinating discovery − the mass of each particle was much, much smaller than that of any known atom.
JJ Thomson, electrons and the Cathode Ray Tube
Cathode rays form when electrons emit from one electrode and travel to another. The transfer occurs due to the application of a voltage in vacuum. Thomson also determined the mass to charge ratio of the electron using a cathode ray tube, another significant discovery. Cathod ray tube, which was used by Thomson to discover the electron.

Cathode Ray Experiment by J. J. Thomson
Thomson's First Cathode Ray Experiment. Thomson had an inkling that the 'rays' emitted from the electron gun were inseparable from the latent charge, and decided to try and prove this by using a magnetic field. His first experiment was to build a cathode ray tube with a metal cylinder on the end. This cylinder had two slits in it, leading ...
Experiments on the Nature of Cathode Rays
A simple representation of a cathode ray tube A cathode ray was the name given to the observation of these electrons when they were incident on the glass coated with fluorescent material behind the cathode. It is important to keep in mind that at the time when cathode rays were observed, scientists were not aware of the existence of electrons.

Cathode Ray Experiment
Cathode rays are a type of radiation emitted by the negative terminal, the cathode, and was discovered by passing electricity through glass tubes from which the air was mostly evacuated. One device used to investigate this phenomenon was a cathode ray tube, the forerunner of the television tube. It is a glass tube from which most of the air has ...
JJ Thompson's Discovery of Electron: Cathode Ray Tube Experiment Explained
In 1896, Thomson wondered if there might have been something wrong with Hertz's experiment with the two plates. Thomson knew that the cathode ray tubes that they had only work if there is a little air in the tube and the amount of air needed depended on the shape of the terminals. Thomson wondered if the air affected the results.

Cathode Ray Tube (CRT)
In 1907, the cathode ray tube was first used in television when Russian scientist Boris Rosing passed a video signal through it to obtain geometric shapes on the screen. Earlier cathode ray tubes used cold cathodes. However, a hot cathode came into existence after being developed by John B. Johnson and Harry Weiner Weinhart of Western Electric.

Yes, J.J. Thomson used cathode rays. He used them in his experiments with cathode ray tubes in order to determine what cathode rays were composed of. He found that they were composed of a ...
Thomson's Discovery of The Electron
Thomson's experiment obtained a value for the charge to mass ratio of cathode rays, which proved their particle nature. In the first part of Thomson's experiment, a pair of charged metal plates was used to create a uniform electric field. When a cathode ray travelled through this field, it was deflected towards the positive plate.
J J Thomson
In 1897, great physician J.J. Thompson, conducted his first cathode ray tube experiment to prove that rays emitted from an electron gun are inseparable from the latent charge. He built his cathode ray tube with a metal cylinder on the other end. The metal had two small diversions (slits), leading to an electrometer that could measure a small ...

Cathode ray tube
Cathode ray tube. Dim the lights and turn on the camera if you're using one. Turn up the energy of the electron beam until the gas inside the globe is clearly glowing. If your CRT doesn't have Helmholtz coils, simply wave the neodymium magnet near the CRT to show the beam bending. You may need to do this quite slowly if the camera is set to ...
Cathode ray
Cathode ray. A beam of cathode rays in a vacuum tube bent into a circle by a magnetic field generated by a Helmholtz coil. Cathode rays are normally invisible; in this demonstration Teltron tube, enough gas has been left in the tube for the gas atoms to luminesce when struck by the fast-moving electrons. Cathode rays or electron beams ( e-beam ...
Definition and History of Cathode Ray
Cathode Ray History. Electron Beams Lead to Discovery of Subatomic Particles. A cathode ray is a beam of electrons in a vacuum tube traveling from the negatively charged electrode (cathode) at one end to the positively charged electrode ( anode) at the other, across a voltage difference between the electrodes. They are also called electron beams.
Cathode ray
A cathode ray is a stream of electrons that are seen in vacuum tubes. It is called a "cathode ray" because the electrons are being emitted from the negative charged element in the vacuum tube called the cathode. A cathode ray tube aims the ray at a point on its screen. They were first observed in 1869 by German physicist Johann Hittorf, and ...
