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.
How heavy is the cathode ray tube?
Could you please explain your question more fully?Is it the last part of a longer question?There are many types and sizes of cathode ray tubes, which weigh different amounts.RegardsGeorge
What is Eugene Godstein's model of the atom?
Eugene Goldstein contributed to the plum pudding model of the atom. This placed negatively charged electrons in a sea of positive charge forming an atom. This came from his experiments with cathode ray tubes and perforated cathodes emitting glows. As cathode rays pass through the perforated holes from anode to cathode, another ray travels in the opposite direction.
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.
Do LCD TVs use cathode ray tubes?

Why was Dalton's model of the atom changed after Thomson's experiment?
John Dalton's atomic theory indicated that atoms were indivisible spheres. When JJ Thomson did his work with cathode ray tubes, he discovered that atoms contain electrons, which meant that the atom is not indivisible, that there are smaller particles within.
Does a cathode ray tube resemble the tubes used in transistor radios?
Transistor radios have NO tubes. They have (guess what) transistors.
Which subatomic particle was discovered to working with cathode-ray tubes?
electron
What can make x rays?
Cathode ray tubes and linear accelerators
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.
Who discovered subatomic particles during work with cathode tubes?
j.j. Thompson
What evidence did J.J Thomson provided about this structure of an atom?
J.J. Thomson provided evidence about the structure of an atom through his discovery of the electron using cathode ray tubes. His experiments showed that electrons are negatively charged particles and are present in all atoms, leading to the development of the plum pudding model of the atom.
