Why do cathode rays move from the negative end of the tube to the positive end?
Because an electron carries a negative charge and in electricity, opposites attract. Particles with a negative charge will be drawn to the positive charge in the cathode tube.
How did JJ Thompson know the charge of the particles?
from his cathode ray tube experiment
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.
How did William crooks know that the glow in the cathode-ray tube resulted from stream of charge particles?
it was deflected by a magnet
How did the cathode's tube experiment lead to the conclusion that atoms contain electrons?
because Thomson saw the ray move from the cathode to the anode so the particles have negatively charge
In the cathode ray tube where do the particles originate?
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 is the nature of charge on cathod rays?
Cathode rays are negatively charged particles, which are typically electrons. These electrons are emitted from the cathode in a vacuum tube and are attracted to the positively charged anode.
What is the particles in Thomson's tube?
In Thomson's tube, also known as the cathode ray tube, the primary particles involved are electrons. These negatively charged particles are emitted from a cathode and are accelerated towards an anode, creating a stream of electrons, or cathode rays. When subjected to electric or magnetic fields, these electrons can be deflected, allowing for the study of their properties and confirming their charge-to-mass ratio. Thomson's experiments led to the discovery of the electron as a fundamental particle of matter.
What is the evidence that show cathode rays consists of charged particles?
One piece of evidence is the observation that cathode rays are deflected by electric and magnetic fields, indicating they carry charge. Further evidence comes from the fact that cathode rays produce X-rays when striking a target, which is consistent with the behavior of charged particles like electrons. Additionally, the ratio of the charge to mass of the particles in cathode rays was found to be the same as that of electrons.
Is the amount of space charge created at the cathode is primarily controlled by the tube current?
The cathode space charge is determined by the voltage on the filament.
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.
