The experiment Cathode Ray Tube (CRT) conducted by J. J. Thomson, is one of the most well-known physical experiments that led to electron discovery. In addition, the experiment could describe characteristic properties, in essence, its affinity to positive charge, and its charge to mass ratio. This paper describes how J is simulated.
Cathode Ray Experiment by J. J. Thomson
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 to electrometers, which could measure ...
J.J. Thomson's Cathode Ray Tube Experiment
J.J. Thomson performed three experiments with cathode ray tubes. First, he used a magnet and electrometer to observe that the cathode rays were indeed electrically charged. Next, he determined ...
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 Tube Experiment
The cathode ray tube experiment performed by J.J. Thomson demonstrated the existence of the electron. Scientist had believed in the existence of a negative particle for some time. So much so, that George Stoney (1891) proposed the name electron for the particle. However, it wasn't till about 1898 that the electron was shown to exist by J.J ...
J.J. Thomson's Cathode Ray Tube Experiment
In 1897, J.J. Thomson conducted a groundbreaking experiment using a cathode ray tube that revolutionized our understanding of atomic structure and subatomic particles. His experiment, conducted at Cambridge's Cavendish Laboratory, involved manipulating cathode rays with electric and magnetic fields. Thomson's custom-made cathode-ray tubes ...
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)
Experiment Summary. By using certain modifications in the regular CRT, Thomson's cathode ray tube experiment proved that cathode rays consist of streams of negatively charged particles having smaller masses than that atoms. It was highly likely for them to be one of the components of atoms.
Thomson's Cathode Ray Experiment
Thomson's Cathode Ray Experiment was a groundbreaking study conducted by J.J. Thomson in 1897 that led to the discovery of the electron as a fundamental particle. In this experiment, Thomson used a cathode ray tube to observe the behavior of cathode rays, which are streams of electrons emitted from a negatively charged electrode. His findings challenged existing atomic models and introduced ...
What did the Cathode Ray Tube Experiment demonstrate?
The outcome of the Cathode Ray Tube Experiment, conducted by J.J. Thomson, was the discovery of the electron. Thomson demonstrated that cathode rays were composed of negatively charged particles, which he called "corpuscles" (later renamed electrons). This experiment provided evidence for the existence of subatomic particles and led to the development of the modern atomic model.

The mean free path for molecules in air was approximately \(10^{-5}\) cm. If the cathode ray traveled so much farther than a molecule before colliding with an air molecule, Thomson argued that it must be much smaller than a molecule. Thomson had shown that cathode rays behave as one would expect negatively charged material particles to behave.
Joseph John "J. J." Thomson
The British physicist Joseph John "J. J." Thomson (1856-1940) performed a series of experiments in 1897 designed to study the nature of electric discharge in a high-vacuum cathode-ray tube, an area being investigated by many scientists at the time. Thomson interpreted the deflection of the rays by electrically charged plates and magnets ...
Understanding Thomson's Cathode Ray Experiment and Its Impact
a. In Thomson's experiment, he observed cathode rays emitted from a cathode in a vacuum tube. By subjecting these rays to perpendicular electric and magnetic fields, he observed deflection. The cathode rays were deflected in a manner consistent with the Lorentz force, caused by their negative charge in the electric field and their movement through the magnetic field.

Cathode Ray Tube Experiment
Cathode Ray Tubes. In the 1890's JJ Thomson investigated cathode rays. Cathode rays get produced by a unique apparatus. It's creatively called a cathode ray tube. The tube is a glass chamber with two metal discs. The metals get connected to a voltage source. The voltage sources cause one disc to become positively charged.
