What are the rays in the cathode ray tubepositive or negative or neutral?

The rays in the cathode ray tube are electrons, so they are negative.


The cathode rays that are produced in an electric discharge tube are?

The cathode ray is nothing but the stream of electrons.


Why were the cathode rays in Thomson's cathode ray tube bent by a magnet?

Because cathode rays are electrons - elementary particles negative electrically charged.


What are cathode rays made of?

Cathode rays are composed of electrons that have emitted from gases inside a cathode ray tube. Cathode rays were determined to be electrons by placing them under the influence of a magnetic field. The ray responded and was attracted to a positive plate.


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.


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.


What did thomsons cathode ray tube experiment demonstrate?

It demonstrated the presence of Cathode/X-Rays experimentally.


In cathode ray tube cathode and anode rays travel opposite to each other but they are not neutralized. why?

There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.


What is the evidence that show cathode rays consists of charged particles?

in a cathode ray tube the cathode rays move towards the anode(positively charged) fixed plate.


Why did the rays move the paddle wheel in cathode ray tube?

momentum of the 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.


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.


Why is the cathode-ray tube in figure 4 connected to a vacuum pump?

A Cathode-ray tube is a vacuum that is used to get the air out. Cathode rays (electrons) cannot penetrate through any significant amount of air.


What type of particle are cathode rays made of?

A cathode ray is an electron. In the cathode-ray tube (i.e. televisions and early monitors), a beam of electrons is aimed at a phosphor-coated surface at the other end of a vacuum tube.


What are the advantages and disadvantages of the cathode ray tube?

what are the advantages and disadvantages of cathode ray tube


Who discovered the cathode ray tube?

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


Why vacuum is created in cathode ray tube?

vaccum is created in the cathode ray tube because the metal inside the cathode tube can react with air


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

Electrons.


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

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


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.


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.


Flow of a cathode ray inside a cathode ray tube?

Electrons flow from cathode to anode


What is the difference between cathode ray tube and cathode ray oscilloscope?

The cathode-ray oscilloscope is an electronic display device containing a cathode-ray tube (CRT), used to produce visible patterns that are the graphical representations of electrical signals while CRT (cathode ray tube) is a tube that uses high voltage to fire electrons at a screen
