Why does fluorescence occur in cathode ray tube
Answers
Answer:
to make sure that those are cathode rays traveling from cathode to anode
Explanation:
at the corners of tube fluorescence material is applied, when rays hit the fluorescence material it glows making sure that these rays are traveling from cathode to anode.
Answer:
Instead, they produced a colorful glow discharge (as in a modern neon light), caused when the electrons struck gas atoms, exciting their orbital electrons to higher energy levels. The electrons released this energy as light. This process is called fluorescence.
Explanation:
Cathode rays are invisible, but their presence was first detected in early vacuum tubes when they struck the glass wall of the tube, exciting the atoms of the glass and causing them to emit light, a glow called fluorescence
