CRTs operated by playing a beam of electrons of varying intensities over a display surface such as a phosphor screen, which formed patterns of light that took the form of characters or images
The two most recognizable types of electron tubes are vacuum tubes and cathode ray tubes. Vacuum tubes are electronic devices that control electrical signals, while cathode ray tubes are used in older television and computer monitors to display images.
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 Thomson conducted the cathode-ray tube experiment in 1911.
The property of the cathode ray that is shown in this scenario is that it possesses a negative charge. The deflection away from the negatively charged object is consistent with the repulsion between like charges in an electric field.
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.
No
Some early flat screen TVs used cathode ray tubes, but the flat faced tubes were harder to make and heaver than the older curved faced tubes. When newer designs (e.g. plasma, LCD, LED) came out that naturally produced flat screens and were lighter weight than cathode ray tubes, they rapidly made flat screen cathode ray tube TVs obsolete.

J.J. Thomson's experiments with cathode ray tubes suggested that electrons have a very small mass compared to other particles.
J. J. ThomsonJ. J. Thomson did the cathode ray experiment where he discovered the existence of electrons.
Cathode ray tubes are the screens of old fashioned televisions and computer monitors.
The electron was discovered by using cathode ray tubes. When it was discovered that the cathode ray diverted away from the negative end of a magnet to the positive end, it revealed that there was a negative particle present in the ray.
Transistor radios have NO tubes. They have (guess what) transistors.
Cathode Ray Tubes are potentially dangerous because they are vacuum sealed and can implode. This can cause the shattered glass to fly outward and also exposes the toxic coating inside of the tube.
