In a cathode ray tube (CRT), the particles, which are electrons, originate at the heated cathode, becoming the so-called cathode rays. The electrons stream off the cathode and rush over to the anode.
What else can I help you with?
In a cathode ray tube where do the particles originate towards what Do they move?
The particles originate from the Cathode in the neck of the tube. They are liberated by a heater. The electrons thus liberated are attracted by the Anode, by applying a high voltage to it. In a CRT there are several anodes, the largest and biggest is formed by a coating inside the tube towards the screen. This attracts and accelerates the electrons in a stream of particles known as a 'cathode ray'. They carry on in a straight line, once accelerated, until they hit the screen and cause a phosphor coating to glow, on the inside surface of the screen. The cathode ray can be bent from it's course, by using electromagnets arranged around the neck of the tube.

Which scientist used a cathode ray tube to discover negatively charged subatomic particles?
The scientist who used a cathode ray tube to discover negatively charged subatomic particles was J.J. Thomson.
How did JJ Thompson know the charge of the particles?
from his cathode ray tube experiment
What following piece of equipment was used by jj Thomson to find electrons?
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.
Where does the thermionic emission occur in cathode rays tube?
Thermionic emission occurs at the cathode in a cathode ray tube, which is a vacuum tube that generates electron beams. When the cathode is heated, electrons are emitted and accelerated towards the anode, leading to the generation of cathode rays within the tube.
How was the electric field used to determine the charge of the cathode ray?
The electric field was used to deflect the cathode rays in a cathode ray tube. By measuring the amount of deflection and knowing the strength of the electric field, the charge-to-mass ratio of the particles in the cathode rays could be calculated. This allowed for the determination of the charge of the particles in the cathode ray.
What is the full meaning of CRT in computer?
A "CRT" is a cathode ray tube. An old style computer monitor (not computer).
What is the flow of a cathode ray inside a cathode ray tube?
Electrons.
Why television are also known as cathode ray tube?
because cathode ray tube is the heart of the television.
Who first invented the cathode ray tube?
The cathode ray tube was invented in 1897 by Ferdinand Braun.
