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.
Why are cathode rays deflected away from a negatively charged plate?
Cathode rays are deflected away from a negatively charged plate because they are negatively charged particles themselves. Like charges repel each other, so the negative cathode rays are pushed away from the negative plate.
If Cathode rays emitted by a piece of silver and a piece of copper illustrate identical properties What is the significance of this observation?
This observation indicates that cathode rays are independent of the material from which they originate, suggesting that they may consist of fundamental particles. This led to the discovery of electrons as components of cathode rays and was a significant step in the development of atomic theory.
Is cathrone rays steams of electron?
yes, cathode rays are streams of electrons
What was the experimental evidence that Thomson had discovered the existence of a subatomic particle when working with cathode rays?
Thomson discovered the electron and proved that it existed without ever being able to see or isolate one. Electrons were the first subatomic particles to be discovered, the first particle of matter identified that was smaller than an atom. This discovery also finally provided some physical proof of, and description of, the basic unit that carried electricity. Thomson attached thin metal plates inside his cathode ray tube to a battery and showed that an electrical field could also deflect cathode rays.
What particle was observed in the cathode rays?
The negatively charged particle called electron.
Who discovered anode and cathode rays?
Cathode rays were discovered by JJ Thomson and carry a negative charge Anode rays were discovered by Goldstein and carry a positive charge.
What did j.j Thomson experiment with?
J.J. Thomson experimented with cathode rays in a vacuum tube, which led to the discovery of the electron in 1897. By measuring the charge-to-mass ratio of electrons, he determined that they were a fundamental particle and were present in all atoms.
How do charged plates affect the path of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
How do charged plates affect the plates of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
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.
Cathode rays all have same negative charge?
True
What would happen to the deflection of the cathode ray if the particle in the rays were heavier?
deflect more
Are cathode rays deflected toward a negatively charged plate in an electric field?
Yes, cathode rays are deflected towards a positively charged plate in an electric field. The negatively charged particles in the cathode rays are attracted to the positive plate, causing the deflection.
What is the charge of the cathode tube particles?
Cathode rays are high speed electrons. So they are negatively charged.
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.
How did Thomson determine that cathode rays are negatively charged?
Thomson observed that cathode rays were deflected by electric and magnetic fields in a manner consistent with them having a negative charge. He measured the charge-to-mass ratio of cathode rays and found it to be the same regardless of the material used for the electrodes, which suggested the charge was a fundamental property of the particles themselves.
