J.J. Thompson discovered the electron, the first of the subatomic particles, using the cathode ray tube experiment. He found that many different metals release cathode rays, and that cathode rays were made of electrons, very small negatively charged particles. This disproved John Dalton's theory of the atom, and Thompson came up with the plum pudding model of the atom.
This is the official Video of Cathode Ray Tube by sir JJ Thomson..
A Cathode ray tube is the forerunner of the television tube. It is a glass tube from which
most of the air has been evacuated.
When the two metal plates are connected to a high-voltage source, the negatively charged plate, called the cathode, emits an invisible ray.
The cathode ray is drawn to the positively charged plate, called the anode, where it passes through a hole and continues traveling to the other end of the tube.
When the ray strikes the specially coated surface, the cathode ray produces a strong fluorescence, or bright light.
When an electric field is applied across the cathode ray tube, the cathode ray is attracted by the plate bearing positive charges. Therefore, a cathode ray must consist of negatively charged particles.
A moving charged body behaves like a tiny magnet, and it can interact with am external magnetic field. The electrons are deflected by the magnetic field.
As expected, when the direction of the external magnet field is reversed, the beam of electrons is deflected in the opposite direction.
In 1897, JJ Thomson, and English physicist, determined the charge-to-mass ratio of an electron.
He adjusted the electric field so that the electrostatic deflection (0E) was the same as the magnetic deflection (0B), and was able to calculate the charge-to-mass ratio of an electron using the following equation:
Where E is the applied electrical field, 0 is the angle of deflection, B is the applied magnetic field, and / is the distance traveled by the cathode rays.
Thomson determined the charge-to-mass ratio of an electron to be -1.76 x 10 eight power coulombs per gram.

Cathode Ray Tube
The Cathode Ray Tube (CRT) is a vacuum tube containing an electron gun (a source of electrons) and a fluorescent screen, with internal or external means to accelerate and deflect the electron beam, used to create images in the form of light emitted from the fluorescent screen. The image may represent electrical waveforms (oscilloscope), pictures (television, computer monitor), radar targets and others.
The CRT uses an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Display technologies without these disadvantages, such as flat plasma displays, liquid crystal displays, DLP, OLED have replaced CRTs in many applications and are becoming increasingly common as costs decline. A cathode ray tube is a vacuum tube which consists of one or more electron guns, possibly internal electrostatic deflection plates, and a phosphor target. In television sets and computer monitors, the entire front area of the tube is scanned repetitively and systematically in a fixed pattern called a raster. An image is produced by controlling the intensity of each of the three electron beams, one for each additive primary color (red, green, and blue) with a video signal as a reference. In all modern CRT monitors and televisions, the beams are bent by magnetic deflection, a varying magnetic field generated by coils and driven by electronic circuits around the neck of the tube, although electrostatic deflection is commonly used in oscilloscopes, a type of diagnostic instrument.

"As the cathode rays carry a charge of negative electricity, are deflected by an electrostatic force as if they were negatively electrified, and are acted on by a magnetic force in just the way in which this force would act on a negatively electrified body moving along the path of these rays, I can see no escape from the conclusion that they are charges of negative electricity carried by particles of matter."

Ask any questions in the comments. Do not attempt to recreate this experiment. The vacuum on this tube is not enough to create a beam that does not glow so bright. This may be considered a "rarified arc in a vacuum" but it still demonstrates the properties of a cathode ray tube. Don't post nasty comments. You may be blocked.

In the mid 1800's scientists successfully passed an electric current through a vacuum in a glass tube. They saw a glow from the tube that seemed to emanate from the negatively charged plate called the cathode. Since scientists didn't know what the glow was they called it a cathode ray. There was debate over whether the cathode ray was a wave phenomenon like light or a stream of negatively charged particles. JJ Thomson effectively resolved the debate in 1897 by performing a clever experiment that determined the charge to mass ratio of the particles making up the cathode ray. He also showed that this same particle was in all different cathode materials so it must be a constituent common to all atoms. This changed our understanding of the atom from the previous billiard ball model to Thomson's plum pudding model of the atom.

Cathode ray tube
The cathode ray tube (CRT) is a vacuum tube containing one or more electron guns, and a phosphorescent screen used to view images. It has a means to accelerate and deflect the electron beam(s) onto the screen to create the images. The images may represent electrical waveforms (oscilloscope), pictures (television, computer monitor), radar targets or others. CRTs have also been used as memory devices, in which case the visible light emitted from the fluorescent material (if any) is not intended to have significant meaning to a visual observer (though the visible pattern on the tube face may cryptically represent the stored data).
The CRT uses an evacuated glass envelope which is large, deep (i.e. long from front screen face to rear end), fairly heavy, and relatively fragile. As a matter of safety, the face is typically made of thick lead glass so as to be highly shatter-resistant and to block most X-ray emissions, particularly if the CRT is used in a consumer product.
Since 2008, CRTs have largely been superseded by newer display technologies such as LCD, plasma display, and OLED, which have lower manufacturing costs, power consumption, weight and bulk.

Cathode ray
Cathode rays (also called an electron beam or e-beam) are streams of electrons observed in vacuum tubes. If an evacuated glass tube is equipped with two electrodes and a voltage is applied, the glass opposite of the negative electrode is observed to glow, due to electrons emitted from and travelling perpendicular to the cathode (the electrode connected to the negative terminal of the voltage supply). They were first observed in 1869 by German physicist Johann Hittorf, and were named in 1876 by Eugen Goldstein Kathodenstrahlen, or cathode rays.
Electrons were first discovered as the constituents of cathode rays. In 1897 British physicist J. J. Thomson showed the rays were composed of a previously unknown negatively charged particle, which was later named the electron. Cathode ray tubes (CRTs) use a focused beam of electrons deflected by electric or magnetic fields to create the image in a classic television set.
Description
Cathode rays are so named because they are emitted by the negative electrode, or cathode, in a vacuum tube. To release electrons into the tube, they first must be detached from the atoms of the cathode. In the early cold cathode vacuum tubes, called Crookes tubes, this was done by using a high electrical potential between the anode and the cathode to ionize the residual gas in the tube; the ions were accelerated by the electric field and released electrons when they collided with the cathode. Modern vacuum tubes use thermionic emission, in which the cathode is made of a thin wire filament which is heated by a separate electric current passing through it. The increased random heat motion of the filament knocks electrons out at the surface of the filament, into the evacuated space of the tube.

The image may represent electrical waveforms (oscilloscope), pictures (television, computer monitor), radar targets and others.
The CRT uses an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Display technologies without these disadvantages, such as flat plasma displays, liquid crystal displays, DLP, OLED have replaced CRTs in many applications and are becoming increasingly common as costs decline. A cathode ray tube is a vacuum tube which consists of one or more electron guns, possibly internal electrostatic deflection plates, and a phosphor target. In television sets and computer monitors, the entire front area of the tube is scanned repetitively and systematically in a fixed pattern called a raster. An image is produced by controlling the intensity of each of the three electron beams, one for each additive primary color (red, green, and blue) with a video signal as a reference. In all modern CRT monitors and televisions, the beams are bent by magnetic deflection, a varying magnetic field generated by coils and driven by electronic circuits around the neck of the tube, although electrostatic deflection is commonly used in oscilloscopes, a type of diagnostic instrument.

In all modern CRT monitors and televisions, the beams are bent by magnetic deflection, a varying magnetic field generated by coils and driven by electronic circuits around the neck of the tube, although electrostatic deflection is commonly used in oscilloscopes, a type of diagnostic instrument.

"As the cathode rays carry a charge of negative electricity, are deflected by an electrostatic force as if they were negatively electrified, and are acted on by a magnetic force in just the way in which this force would act on a negatively electrified body moving along the path of these rays, I can see no escape from the conclusion that they are charges of negative electricity carried by particles of matter."

Ask any questions in the comments. Do not attempt to recreate this experiment. The vacuum on this tube is not enough to create a beam that does not glow so bright. This may be considered a "rarified arc in a vacuum" but it still demonstrates the properties of a cathode ray tube. Don't post nasty comments. You may be blocked.

In the mid 1800's scientists successfully passed an electric current through a vacuum in a glass tube. They saw a glow from the tube that seemed to emanate from the negatively charged plate called the cathode. Since scientists didn't know what the glow was they called it a cathode ray. There was debate over whether the cathode ray was a wave phenomenon like light or a stream of negatively charged particles. JJ Thomson effectively resolved the debate in 1897 by performing a clever experiment that determined the charge to mass ratio of the particles making up the cathode ray. He also showed that this same particle was in all different cathode materials so it must be a constituent common to all atoms. This changed our understanding of the atom from the previous billiard ball model to Thomson's plum pudding model of the atom.

Discovery of cathode rays and Anode rays and J.J Thomson atomic Model
Cathode rays (also called an electron beam or e-beam) are streams of electrons observed in vacuum tubes. If an evacuated glass tube is equipped with two electrodes and a voltage is applied, the glass opposite of the negative electrode is observed to glow, due to electrons emitted from and travelling perpendicular to the cathode (the electrode connected to the negative terminal of the voltage supply). They were first observed in 1869 by German physicist Johann Hittorf, and were named in 1876 by Eugen Goldstein Kathodenstrahlen, or cathode rays.[1][2] Electrons were first discovered as the constituents of cathode rays. In 1897 British physicist J. J. Thomson showed the rays were composed of a previously unknown negatively charged particle, which was later named the electron. Cathode ray tub... -

It has a means to accelerate and deflect the electron beam(s) onto the screen to create the images. The images may represent electrical waveforms (oscilloscope), pictures (television, computer monitor), radar targets or others. CRTs have also been used as memory devices, in which case the visible light emitted from the fluorescent material (if any) is not intended to have significant meaning to a visual observer (though the visible pattern on the tube face may cryptically represent the stored data).

History Of Television Documentary - Image Of Sin - National TV A television, generally described as TV, telly or television, is a telecommunication medium made use of for transmitting sound with relocating images in grayscale (black-and-white), colour, or in three measurements. It can refer to a tv set, a tv program, or the tool of tv transmission. Tv is a mass tool, for amusement, instructional tv, news as well as marketing. Television became readily available in unrefined speculative types in the late 1920s. After The second world war, a better kind ended up being preferred in the United States and Britain, and tv set ended up being widespread in houses, companies, and also institutions. During the 1950s, tv was the primary medium for affecting popular opinion. In the mid-1960s, shade ... -

If an evacuated glass tube is equipped with two electrodes and a voltage is applied, the glass opposite of the negative electrode is observed to glow, due to electrons emitted from and travelling perpendicular to the cathode (the electrode connected to the negative terminal of the voltage supply). They were first observed in 1869 by German physicist Johann Hittorf, and were named in 1876 by Eugen Goldstein Kathodenstrahlen, or cathode rays.[1][2]
Electrons were first discovered as the constituents of cathode rays. In 1897 British physicist J. J. Thomson showed the rays were composed of a previously unknown negatively charged particle, which was later named the electron. Cathode ray tubes (CRTs) use a focused beam of electrons deflected by electric or magnetic fields to create the image in a classic television set.
Goldstein used a gas discharge tube which had a perforated cathode. When a high electrical potential of several thousand volts is applied between the cathode and anode, faint luminous "rays" are seen extending from the holes in the back of the cathode. These rays are beams of particles moving in a direction opposite to the "cathode rays," which are streams of electrons which move toward the anode. Goldstein called these positive rays Kanalstrahlen, "channel rays" or "canal rays", because they were produced by the holes or channels in the cathode. In 1907 a study of how this "ray" was deflected in a magnetic field, revealed that the particles making up the ray were not all the same mass. The lightest ones, formed when there was some hydrogen gas in the tube, were calculated to be about 1840 times as massive as an electron. They were protons.
The Plum Pudding Model was a model of the atom that incorporated the recently discovered electron, and was proposed by J. J. Thomson in 1904, it was also known as J J Thomson's Atomic Model. Thomson had discovered the electron in 1897. The plum pudding model was abandoned after discovery of the atomic nucleus. The plum pudding model of the atom is also known as the Blueberry Muffin Model.
In this model, the atom is composed of electrons (which Thomson still called "corpuscles", though G. J. Stoney had proposed that atoms of electricity be called "electrons", in 1894[1]) surrounded by a soup of positive charge to balance the electrons' negative charges, like negatively charged "raisins" surrounded by positively charged "pudding". The electrons (as we know them today) were thought to be positioned throughout the atom, but with many structures possible for positioning multiple electrons, particularly rotating rings of electrons (see below). Instead of a soup, the atom was also sometimes said to have had a "cloud" of positive charge. With this model, Thomson abandoned his earlier "nebular atom" hypothesis in which the atom was composed of immaterial vortices. Now, at least part of the atom was to be composed of Thomson's particulate negative "corpuscles", although the rest of the positively charged part of the atom remained somewhat nebulous and ill-defined.
The 1904 Thomson model was disproved by the 1909 gold foil experiment of Hans Geiger and Ernest Marsden. This was interpreted by Ernest Rutherford in 1911[2] [3] to imply a very small nucleus of the atom containing a very high positive charge (in the case of gold, enough to balance about 100 electrons), thus leading to the Rutherford model of the atom. Although gold has an atomic number of 79, immediately after Rutherford's paper appeared in 1911 Antonius Van den Broek made the intuitive suggestion that atomic number is nuclear charge. The matter required experiment to decide. Henry Moseley's work showed experimentally in 1913 (see Moseley's law) that the effective nuclear charge was very close to the atomic number (Moseley found only one unit difference), and Moseley referenced only the papers of Van den Broek and Rutherford. This work culminated in the solar-system-like (but quantum-limited) Bohr model of the atom in the same year, in which a nucleus containing an atomic number of positive charge is surrounded by an equal number of electrons in orbital shells. Bohr had also inspired Moseley's work.

The cathode ray tube (CRT) is a vacuum tube containing one or more electron guns (a source of electrons or electron emitter) and a fluorescent screen used to view images. It has a means to accelerate and deflect the electron beam(s) onto the screen to create the images. The images may represent electrical waveforms (oscilloscope), pictures (television, computer monitor), radar targets or others. CRTs have also been used as memory devices, in which case the visible light emitted from the fluorescent material (if any) is not intended to have significant meaning to a visual observer (though the visible pattern on the tube face may cryptically represent the stored data).
The CRT uses an evacuated glass envelope which is large, deep (i.e. long from front screen face to rear end), fairly heavy, and relatively fragile. As a matter of safety, the face is typically made of thick lead glass so as to be highly shatter-resistant and to block most X-ray emissions, particularly if the CRT is used in a consumer product.

History Of Television Documentary - Image Of Sin - National TV
A television, generally described as TV, telly or television, is a telecommunication medium made use of for transmitting sound with relocating images in grayscale (black-and-white), colour, or in three measurements. It can refer to a tv set, a tv program, or the tool of tv transmission. Tv is a mass tool, for amusement, instructional tv, news as well as marketing.
Television became readily available in unrefined speculative types in the late 1920s. After The second world war, a better kind ended up being preferred in the United States and Britain, and tv set ended up being widespread in houses, companies, and also institutions. During the 1950s, tv was the primary medium for affecting popular opinion. In the mid-1960s, shade broadcasting was introduced in the US as well as most other industrialized countries. The accessibility of storage media such as VHS tape (1976), DVDs (1997), and also high-def Blu-ray Discs (2006) turned on customers to enjoy documented product such as motion pictures. At the end of the initial decade of the 2000s, digital television transmissions greatly increased in appeal. One more property development was the action from standard-definition tv (SDTV)(576i, with 576 interlaced lines of resolution and 480i) to high-def television (HDTV), which offers a resolution that is considerably greater. HDTV could be sent in different layouts: 1080p, 1080i and also 720p. Given that 2010, with the development of wise tv, Web tv has actually enhanced the accessibility of tv programs and also flicks using the Net via services such as Netflix, iPlayer, Hulu, Roku as well as Chromecast.
In 2013, 79 % of the globe's households possessed a television. The replacement of early bulky, high-voltage cathode ray tube (CRT) screen displays with small, energy-efficient, flat-panel alternative technologies such as plasma display screens, LCDs (both fluorescent-backlit and LED), as well as OLED display screens was an equipment revolution that began with computer system displays in the late 1990s. The majority of Television Set marketed in the 2000s were flat-panel, generally LEDs. Significant manufacturers revealed the discontinuation of CRT, DLP, plasma, as well as fluorescent-backlit LCDs by the mid-2010s. LEDs are anticipated to be changed gradually by OLEDs in the near future. Also, significant makers have revealed that they will progressively create clever TV sets in the mid-2010s. Smart TVs with integrated Net as well as Internet 2.0 features are expected to become the leading form of tv by the late 2010s.
Television signals were initially dispersed only as terrestrial tv utilizing high-powered radio-frequency transmitters to transmit the signal to individual tv receivers. Alternatively tv signals are distributed by co-axial cable or optical fibre, satellite heating and cooling units and also through the Net. Until the very early 2000s, these were sent as analog signals yet countries began switching to digital, this transition is expected to be completed around the world by late 2010s. A common television is composed of several internal digital circuits, consisting of a receiver for obtaining as well as translating program signals. An aesthetic display screen tool which does not have a tuner is correctly called a video clip screen instead compared to a tv.
