A type of vacuum tube that forms an electron beam (aka cathode ray) instead of just a diffuse cloud of electrons. There are literally millions of kinds of cathode ray tubes designed for various purposes:
- x-ray tube
- picture tube
- vidicon tube
- iconoscope tube
- image orthicon tube
- image dissector tube
- williams tube (a type of DRAM used in early computers)
- oscilloscope tube
- graphechon tube (a dual CRT used for video scan conversion, e.g. 50Hz frames to 60Hz frames, circular radar scan to rectangular scan)
- etc.
What else can I help you with?
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.
Do LCD TVs use cathode ray tubes?
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.
Does a cathode ray tube resemble the tubes used in transistor radios?
Transistor radios have NO tubes. They have (guess what) transistors.
What makes cathode-ray tubes dangerous?
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.
What were the two main problems of using vacuum tubes in computers?
Valves, or vacuum tubes, were large, generated tremendous heat, and were prone to failure.Vacuum tubes worked much like transistors, but required a filament to heat the cathode so that electrons could flow through the plate when there were the proper grid voltages for that. If the cathode heater burned out, the cathode would not work, and the tube would need to be replaced. Comparing to a PNP or NPN transistor, the cathode would be equivalent to the emitter, the plate would compare to the base, and the grid would computer to the collector. Comparing to an FET, the cathode would be the source, the grid would compare the the gate, and the plate would compare to the drain.

Do plasma T.V's use cathode ray tubes?
No
Do all vacuum tubes light up?
No, there are some cold cathode vacuum tubes. These do not light.

How do scientists detect cathode rays?
Cathode rays are found in vacuum tubes. Scientists are able to view them when they are a negative cathode because they emit a light and can glow.
Does a cathode ray tube resemble the tubes used in transistor radios?
Transistor radios have NO tubes. They have (guess what) transistors.
What did J.J. Thomson's experiments with cathode ray tubes imply about the mass of an electron?
J.J. Thomson's experiments with cathode ray tubes suggested that electrons have a very small mass compared to other particles.
What can make x rays?
Cathode ray tubes and linear accelerators
Which subatomic particle was discovered to working with cathode-ray tubes?
electron
What makes cathode-ray tubes dangerous?
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.
Who discovered subatomic particles during work with cathode tubes?
j.j. Thompson
What is an example of a cathode ray tube found in most American homes?
Cathode ray tubes are the screens of old fashioned televisions and computer monitors.
