What else can I help you with?
Who first invented the cathode ray tube?
The cathode ray tube was invented in 1897 by Ferdinand Braun.
Why is the cathode-ray tube in figure 4 connected to a vacuum pump?
A Cathode-ray tube is a vacuum that is used to get the air out. Cathode rays (electrons) cannot penetrate through any significant amount of air.
Is cathode ray tube and electron tube same?
Yes they are the same. A cathode ray tube (CRT) uses an electron gun to "shoot" electrons from the cathode to specific positions on the anode of the CRT.
What is the modern day name for cathode ray tube?
The Cathode Ray Tube is called CRT, but I don't know of any "modern day" name. I know it was discovered by J.J. Thomson, who discovered electrons through the Cathode Ray Tube.
What prompted early scientists to propose that the ray of the cathode ray tube was due to the cathode?
The electron had already been discovered. It took little imagination to "see" that the cathode ray was the beam of electrons that originated from the cathode. And the beam was controlled using techniques based directly on what was correctly understood about the electron. The cathode ray could only be an electron beam generated at the cathode. Conventional elctric current flow is usually thought of as flowing from positive to negative, but at the quantum level; due to electrons having a negative charge; technically they really flow from negative to positive, and this is apparent in the cathode ray tube. Its the negatively charged electrons that glow in a cathode ray tube, and do so from the negative terminal, or cathode, hence the name.
What following piece of equipment was used by jj Thomson to find electrons?
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.
Which of these appliances uses cathode ray tube - electric fan refrigerator or rice cooker?
None of these appliances use a cathode ray tube. Older type TVs used a cathode ray tube, its common name was the picture tube.
What is the full meaning of CRT in computer?
A "CRT" is a cathode ray tube. An old style computer monitor (not computer).
What is the flow of a cathode ray inside a cathode ray tube?
Electrons.
Why television are also known as cathode ray tube?
because cathode ray tube is the heart of the television.
Who first invented the cathode ray tube?
The cathode ray tube was invented in 1897 by Ferdinand Braun.
Which scientist used a cathode ray tube to discover negatively charged subatomic particles?
The scientist who used a cathode ray tube to discover negatively charged subatomic particles was J.J. Thomson.
He conducted the cathode-ray tube experiment?
J.J Thomson conducted the cathode-ray tube experiment in 1911.
When did Cathode ray tube amusement device happen?
Cathode ray tube amusement device happened in 1947.
