The discharge tube helps to produce the cathode ray which can only be done by minimizing the pressure and maximizing the potential difference. First of all the discharge tube of 25-50cm is taken and having the diameter 3-5 cm is taken. They are made in such a way having the pressure pump to taken out. The one end is make cathode and other end is made anode. The positive terminal is made anode and the negative end is made cathode. So under various pressure it works differently so they are as follows.
When the pressure is maintained to be 10mm of hg then it produces a glowing light which is thin and curve in nature so called blue strimmer.
Similarly when the pressure is reduces to 5mm of hg then the wide rays of light is formed this wide light of rays is known as geissler discharge which color depends upon the nature of the gas.
When the pressure is again minimized to 2 mm of hg, then at this condition the rays of light is developed from the anode towards the cathode it is known as positive column
When the pressure is again minimized to 1 mm of hg, then at this condition the cathode forms a glow this is called as the negative glow. In the same way due to no ionization occurrence there is no loss of energy so form a dark space this dark space is known as the faradays dark space.
When the pressure is minimized to 0.5 mm of hg then in this condition the negative glow moves towards the anode and similarly the cathode forms a glow this glow is known as the cathode glow and the space between this glow is known as the crooks dark space.
Finally when the pressure is minimized to 0.01 mm of hg then at this condition the invisible ray of light is formed then this ray is known as cathode ray. In this way we obtain the cathode ray.
On further decreasing pressure we obtain no discharge of rays. Hence in this way the discharge tube works. The application of this tube is very vast. It is applied in most of our day to day life. Specially to those items that emits the light. So in this way the discharge tube works.
