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.
J.J. Thompson used cathode ray tube to discover what?
Electrons.
What is the significance of the cathode ray diagram in understanding the behavior of electrons in a cathode ray tube?
The cathode ray diagram is significant because it shows the path of electrons in a cathode ray tube. By understanding this diagram, scientists were able to discover the behavior of electrons, leading to advancements in technology like television and computer monitors.
What piece of equipment did JJ Thomson use in his atomic theory experiment?
JJ Thomson used a cathode ray tube in his atomic theory experiment, known as the cathode ray experiment. By observing the behavior of cathode rays in the tube, he was able to discover the existence of electrons and propose the plum pudding model of the atom.
What did thomsons cathode-ray tube experiments help scientists learn?
Thomson's cathode-ray tube experiments helped scientists discover the existence of negatively charged particles, or electrons, and their fundamental role in the structure of atoms. This laid the foundation for the development of the atomic model and contributed to the field of particle physics.
What is the flow of a cathode ray inside a cathode ray tube?
Electrons.
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.
Who discover the cathode ray?
The cathode ray tube was not discovered it was invented by Ferdinand Braun
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 were electrons produced from the cathode ray ube?
Electrons were produced in a cathode ray tube by applying a high voltage to the cathode, causing electrons to be emitted through thermionic emission. These electrons were then accelerated towards the anode by the electric field within the tube, creating a beam of electrons known as the cathode ray.
What is Thompson's cathode ray?
homson conducted a series of experiments with cathode rays and cathode ray tubes leading him to the discovery of electrons and subatomic particles. Thomson used the cathode ray tube in three different experiments.
What is the direction of current in picture tube of TV?
A cathode ray tube (CRT) emits light when electrons strike the front of the glass tube that is covered in a phosphor coating. The front of the tube is the anode of the tube. The electrons are fired from the rear of the tube by an electrode called the cathode. The electrons are formed into a beam or ray, hence the name of cathode ray tube. Although the electrons travel from the rear of the tube to the front, or from the cathode to the anode, conventional current actually flows the opposite direction. So, the current, as measured in amps will flow from the anode to the cathode.
