J.J. Thomson used the cathode ray. Thomson's cathode ray experiment was when he shot a narrow beam of electrons through a cylindrical tube and deflected the electrons off of electric and magnetic fields, thus measuring the effects that those fields had on the direction of the beam.

Who invented the cathode ray tube in the 1970s?
William Crookes invented cathode ray tubes.The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897.
What did the cathode ray tube tell us about atomic structure?
because Thomson saw the ray move from the cathode to the anode so the particles have negatively charge
What year were twinkies invented?
they were invented either in 1897 or in 1930.
Who invented fiberglass insulation in 1897?
Russell games Slayter

What particle was found using a cathode ray tube?
British scientist Sir Joseph J. Thomson discovered in 1897 that cathode rays were made up of what are now known as electrons.
What were j.j Thomson ideas called?
In 1897 J.J. Thomson discovered the electron by experimenting with a cathode ray tube.
Which scientist did experiments involving a form of cathode ray tube?
It was the investigator J. J. Thomson who did experiments with an early cathode ray tube. You'll find a link below.
What late 1800's scientist found the electron and other smaller particles?
J.J. Thompson
When was the cathode ray tube invented?
1897.
What did jj thomas discover?
J.J.Thomas discovered that atoms have negatively charged particles called electrons. He discovered this using the Cathode Ray. The cathode ray is a beam of electrons emitted by the cathode of an electrical discharged tube.
Which particle did j.j. Thomson discover?
The first discovery of a subatomic particle would come in 1897, when J.J. Thompson first discovered evidence for the existence of the electron.
Who first invented the cathode ray tube?
The cathode ray tube was invented in 1897 by Ferdinand Braun.
Who discovered cathode ray?
The inventor of the cathode ray tube was Kalman Tihanyi. Tihanyi was a Hungarian physicist and inventor, born in Slovakia in 1897.
What subatomic particle was first discovered?
This particle was the electron in 1897 (J.J. Thomson).
Who isolated the electron first?
The electron was identified and assigned the negative charge in 1897 by J.J. Thomson and his team of British physicists. They performed experiments indicating that cathode rays really were unique particles, rather than waves, atoms or molecules as was believed earlier.
Who invented the cathode ray oscilloscope?
Karl Ferdinand Braun in 1897
