J.J. Thomson conducted a cathode-ray experiment suggesting that cathode rays were made of negatively charged particles(electrons) that came from the inside of atoms.
Thomson. William Crookes and others early experimented with the cathode ray tube, and thus discovered the electron.

How are cathode rays originated?
its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
What is a device which receives electrical impulses and restores them to a visual form with a modified cathode ray tube?
That would be a CRT Monitor (CRT stands for Cathode Ray Tube), or the big clunky monitor that you had such a hard time getting rid of when you got your LCD
What are the Adavantages and disadvantages of vacuum tube?
when the vacuum sucks up things it goes through the tube and into the bag ...Unless you are talking about electronics, then a vacuum tube is used to form an amplifying circuit. Some tubes can emit cathode rays onto a screen (Cathode Ray Tube = CRT) to display a picture and some can function as diodes to regulate current flow.
What are parts of Rotating anode dual focus x-ray tube?
A cathode ray tube will emit electrons boiled off a heater located in the cathode area. As electrons leave the cathode traveling to a more positive potential located at the plate a grid of negative potential can deflect, impede these electrons flow.
What did blaise pascal associated?
Here are a few memorable concepts/experiments/inventions associated with him: 1. Pascal's Triangle (Mathematics) 2. Developed a theory of definition (Mathematics) 3. Built the Pascal's theorem on hexagons. (Mathematics) 4. Invented the hydraulic press. (Inventions) 5. Invented the modern syringe. (Inventions) 6. Invented a primitive form of roulette. (Inventions) 7. Constructed a mechanical calculator which is referred to as the "Pascaline." (Inventions) 8. Did the famous barrel experiment. (Experiments)
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 should a scientist do after he or she experiments?
Record the data and form a conclusion based on the results.
Is scientist a plural word?
No, "scientist" is a singular noun used to refer to an individual who conducts scientific research or experiments. The plural form of "scientist" is "scientists."
What is the plural possessive form of experiments?
The plural possessive form of "experiments" is "experiments'."
Do metals form at the anode or cathode?
Metals typically form at the cathode during electrolysis. This is because positively charged metal ions are attracted to the negatively charged cathode where they gain electrons and deposit as solid metal.
How scientist try to answer questions that cannot be tested with experiments?
To answer a specific question, scientist form a hypothesis. If the hypothesis cannot be testable or answered, they'll give you a prediction of what will most likely happen from the results of the hypothesis.
What is cathode ray reader?
a cathode ray reader is a device that can recognize beams of electrons in analog form and interpret them into digital form
How do scientist form a laws?
What happens is Scientists conduct experiments and if all the Scientists who conducted the same experiment come up with the same results, the call it a LAW.
How do you know the students in the above study are acting as scientist?
Students could be seen to be acting as scientist if they are following the scientific method - Make observations, postulate a hypothesis, and form and complete experiments or further observations to confirm or refute that hypothesis.
What is the plural possessive for experiments?
The plural possessive form of "experiments" is "experiments'".
How do cathode rays form?
Cathode rays are the emission of free electrons form the negative pole of an electric circuit. To get this to happen you need to warm the cathode and place it in a vacuum tube with a high voltage across it. The electron then jump form the cathode and fly across the empty tube to the anode (positive end). They may be bent by magnetic fields in flight.
