What is the modern day name for cathode ray tube?

The Cathode Ray Tube is called CRT, but I don't know of any "modern day" name. I know it was discovered by J.J. Thomson, who discovered electrons through the Cathode Ray Tube.


What did jj tomson discover?

J.J.Thomas discovered that atoms have negatively charged particles called electrons. He discovered this using the Cathode Ray. The cathode ray is a beam of electrons emitted by the cathode of an electrical discharged tube.


Why are electrons attracted to the cathode in a cathode ray tube?

They are not attracted to the cathode. Electrons are repelled by the cathode.


Who discovered negatively charged electrons using a cathode ray tube?

JJ Thomson.


Who discovered the cathode ray tube?

The cathode ray tube was not discovered it was invented by Ferdinand Braun


What pieces of equipment was J J Thomson use when he discovered electrons?

JJ Thomson discovered electrons using a cathode ray tube.


Which scientist did experiments involing a form of cathode ray tube?

J.J. Thomson used cathode ray tubes to prove the existence of electrons.


What did Thomson measure in his experiments with a cathode ray tube?

Joseph John Thomson was an English physicist who is credited to have discovered electrons. In his experiments with a cathode ray tube, he measure the mass to charge ratio of the cathode rays.


The rays produced in a cathode tube in early experiments were?

The rays produced in a cathode tube in early experiments were actually just streams of electrons. They had a negative charge, which was discovered by JJ Thomson when he placed a magnet next to his cathode ray tube and say the ray bend.


How would the electrons produced in a cathode-ray tube filled with neon gas compare with the electrons produced in a cathode-ray tube filled with chlorine gas?

How would the electrons produced in a cathode-ray tube filled with neon gas compare with the electrons produced in a cathode-ray tube filled with chlorine gas?


What is the flow of a cathode ray inside a cathode ray tube?

Electrons.


What did the cathode ray tube prove?

In 1897, British scientist JJ Thomson's experiments with the cathode ray tube proved that the atom contains subatomic particles called electrons. Before that it was believed that atoms were indivisible.


In a 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.


Does a cathode ray tube consists of a stream of protons?

No, a cathode ray tube consists of a stream of electrons.


In a cathode-ray tube where do the particles originate?

In a cathode-ray tube, the particles originate from a cathode. The cathode is the negative terminal. The particles are actually electrons.


Flow of a cathode ray inside a cathode ray tube?

Electrons flow from cathode to anode


Emitted from a cathode ray tube?

electrons


What Scientist did experiments involving a form of cathode ray tube?

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.


What is a cathode ray?

# A stream of electrons emitted by the cathode in electrical discharge tubes. # One of the electrons that is emitted in a stream from a cathode-ray tube.


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.


Who discovered CRT?

cathode ray-tube was discovered by J.J. thomson.
