Who did JJ Thomson work with?
Thomson worked in the Cavendish Laboratory after graduation, under the tutelage of Lord Rayleigh. He quickly earned a membership in the prestigious Royal Society and was appointed Rayleigh’s successor as the Cavendish Professor of Physics at the age of 28.
What was Thomas working with when he discovered the cathode rays?
the electron
Thomson discovered the electron by experimenting with a Crookes, or cathode ray, tube. He demonstrated that cathode rays were negatively charged. In addition, he also studied positively charged particles in neon gas.
Who was involved in the cathode ray experiment?
physicist J. J. Thomson
In 1897, British physicist J. J. Thomson showed that cathode rays were composed of a previously unknown negatively charged particle, which was later named the electron. Cathode-ray tubes (CRTs) use a focused beam of electrons deflected by electric or magnetic fields to render an image on a screen.
Did JJ Thomson work with other scientists?
Thomson was knighted in 1908, becoming Sir J. J. J. J. Thomson died at age 83, on August 30, 1940. His ashes were buried in the Nave of Westminster Abbey, joining other science greats such as Isaac Newton, Lord Kelvin, Charles Darwin, Charles Lyell, and his friend and former research worker Ernest Rutherford.
Who was J.J. Thomson and what was the nature of his work?
Who was J.J. Thomson, and what was the nature of his work? He was a British physicist who attempted to investigate the interior of atoms by experimenting with electrical currents inside glass tubes. More specifically, he sought to determine the mystery behind “cathode rays.”
What did J.J. Thomson do with cathode ray tubes?
Summary. J.J. Thomson’s experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons.

How did JJ Thomson experiment work?
J.J. Thomson’s experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged “soup.”
Who invented cathode ray?
Cathode-ray tube/Inventors
The first cathode ray tube scanning device was invented by the German scientist Karl Ferdinand Braun in 1897. Braun introduced a CRT with a fluorescent screen, known as the cathode ray oscilloscope. The screen would emit a visible light when struck by a beam of electrons.
How did JJ Thomson discover the cathode ray?
Thomson determined that charged particles much lighter than atoms, particles that we now call electrons made up cathode rays. Cathode rays are formed when electrons emitted from one electrode and travel to another when a voltage is applied in a vacuum.
How did JJ Thomson come up with the electron?
How did JJ Thomson find the electron? In the year 1897 J.J. Thomson invented the electron by playing with a tube that was Crookes, or cathode ray. He had shown that the cathode rays were charged negatively. Thomson realized that the accepted model of an atom did not account for the particles charged negatively or positively.
Who was j.j.thomson and what did he do?
See Article History Alternative Title: Sir Joseph John Thomson J.J. Thomson, in full Sir Joseph John Thomson, (born December 18, 1856, Cheetham Hill, near Manchester, England—died August 30, 1940, Cambridge, Cambridgeshire), English physicist who helped revolutionize the knowledge of atomic structure by his discovery of the electron (1897).
How did the cathode ray experiment lead to electron discovery?
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. J.
