A group of electrons
Cathode Ray
Anode ray is positive and cathode ray is negative
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.
A: glass and rare earths
Electrons.
The cathode ray tube was not discovered it was invented by Ferdinand Braun
The cathode ray experiment helped discover electrons
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.
A "CRT" is a cathode ray tube. An old style computer monitor (not computer).
because cathode ray tube is the heart of the television.
The cathode ray tube was invented in 1897 by Ferdinand Braun.
No, the cathode ray is faster than the speed of light.
