How was the Cathode Ray Tube Amusement device invented?
Cathode ray tube amusement device was created in 1947.
What is the negatively charged electrode of a cathode ray tube?
The negatively charged electrode of a cathode ray tube (CRT) is the cathode. The tube is a cathode ray tube, and electrons stream off the cathode, are accelerated across the evacuated space and "directed" either electromagnetically or electrostatically, and then strike the phosphor coating on the positively charged anode at a "location" determined by the "directing" elements.
Why deflection is necessary in cathode ray tube?
It is not necessary in a cathode ray tube, it is a side effect and is needed in the calculations to ensure that there are no errors.
Can an animal see electrons emitted by a cathode ray tube?
no
What are the rays in the cathode ray tubepositive or negative or neutral?
The rays produced in a cathode tube in early experiments were actually just streams of electrons. They had a negative charge, which was discovered by JJ Thomson when he placed a magnet next to his cathode ray tube and say the ray bend.
Who first invented the cathode ray tube?
