Cathode Ray experiment (1 Viewer)

how much in detail do we need to know about the experiment? bascially i know that a tube of 1kpa produces striation patterns and a 0.01kpa tube produces a green glow near the anode. Is this enough information for me to answer the question adequately? or should i also study the different patterns in the other tubes ranging between 0.01 to 1kpa?

From stirations to green glow there isnt much at all bar an increase in the dark spaces.

At higher pressure you will get streamers which travel the whole length down the tube.
