What else can I help you with?
What is the stream of particles originating from a cathode in a vacuum tube?
Not sure of the question, but *electrons flow from cathode to plate in a CRT. A deflection coil guides the electron beam to various areas of the screen. Some CRTs use electrostatic deflection, where the beam is deflected by four grids that steer the beam.
Cathode rays were shown to be a stream of?
Cathode rays are electrons.
What is the negatively charged electrode of a cathode ray tube?
The negatively charged electrode of a cathode ray tube (CRT) is the cathode. The tube is a cathode ray tube, and electrons stream off the cathode, are accelerated across the evacuated space and "directed" either electromagnetically or electrostatically, and then strike the phosphor coating on the positively charged anode at a "location" determined by the "directing" elements.
What are the role of cathode tubes in atom?
cathode tubes were used to detect the particle in an atom & found that negatively charged particles(electrons) are there in an atom.
How are cathode rays originated?
its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
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 stream of particles originating from a cathode in a vacuum tube?

Is cathode rays are material particles?
Cathode rays are streams of electrons that travel from the negatively charged cathode to the positively charged anode in a cathode ray tube. They are not material particles in the traditional sense because they do not have mass or volume, but rather behave as electron beams.
What does a cathode ray consists of?
A cathode ray consists of a stream of electrons generated by heating a cathode. These electrons are accelerated and focused by electric and magnetic fields before hitting a phosphorescent screen to produce a visible image.
What did J J. Thomsons experiment show?
Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.
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
Cathode rays were shown to be a stream of?
Cathode rays are electrons.
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.
How did Thomson know that the glow in the CTR was from a stream of charged particles?
Thomson knew that the glow in the cathode ray tube (CRT) was from a stream of charged particles because the particles were deflected by electric and magnetic fields, indicating they were negatively charged. By measuring the deflection of the particles, he was able to calculate the charge-to-mass ratio of the particles, leading to the discovery of the electron.
Why cathode ray are not electro-magnetic waves?
A cathode ray is a stream of electrons, not a stream of photons like the electromagnetic wave. It's a different type of particle. The electrons don't move at light speed in a vacuum; also, they are electrically charged.
How did J J Thomson show that cathode rays are different from light?
Thomson appreciated in 1897 that the cathode rays are formed from negative electrically charged very small particles. These particles are the electrons. From this Thomson concluded that the atom is not indivisible and also that the atom must contain and a positive charged particle.
How did thomas discover the electron?
J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
