what does the atmospheric pressure of a gas in a CRT have to do with the thickness of the visible cathode rays?
We observed different cathode ray tubes with different atmospheric pressures, the ones with the least atmospheric pressures had very spread out not as dense sort of cathode ray tubes, and as the tubes atmospheric pressures increased the cathode rays seemed to become thinner, similar to that of a spark in air.
Is it correct to think that the denser the atmospheric pressure, the thinner the spark? and thats why a spark in air is so fine? and why does this happen?
also is the spark in air a cathode ray?
thanx in advance.
