why do you use of discharge tube in study of cathode rays?
Answers
Answer:
A discharge tube is an arrangement of electrodes in a gas within an insulating, temperature-resistant envelope. A discharge tube is an electrical device in which current flow is by electrons and ions in an ionized gas, as in a fluorescent light or a neon tube.

your answer is here !
Explanation:
Simplistically, a discharge tube is the generic term for all of them (including cathode ray tubes, and anode ray tubes).
However, a discharge tube probably contains a highly rarefied gas, and that was the main object of the experiment: to study the properties of that gas under such conditions.
Cathode rays are usually just electrons, and you normally want them to travel unimpeded. So the tube probably aims to contain a vacuum, rather than a rarefied gas for study.
