I am considering the cathode ray tube of the set up, when the cathode rays were discovered
Voltage = Very High
Gas = any
Atmospheric Pressure = We change
(In the following example i am just changing the atmospheric pressure everything else is kept same)
At
1 atmospheric pressure (atm) -> Tube Does not glow
0.1 atm -> The whole tube lightens
0.01 atm -> The tube glows at the anode end (Glowing is shown as there is a detector coating of ZnS)
[Note: I don't have this set-up this is just taken by me from theory]
My Question: why when i am just reducing the atm from 1 to 0.01 first it is not glowing then it glows completely and after that it glow just at one end. Why so?
[I am asking this question here because on chemistry forum i was suggested by someone to post it here too as it was related to plasma and people over here could help me better. Link to my question on chemistry forum]
