Why should argon be at low pressure in the geiger muller tube?
Argon is used in the Geiger-Muller tube as a quenching gas to stop the discharge of ions after each pulse. Keeping argon at low pressure allows for efficient quenching of the ionization process. Higher pressure could interfere with the detection process by preventing the resetting of the tube after each detection event.
Why it is necessary to decrease the pressure in discharge tube to get cathode rays?

Why discharge tube appears dark at very low pressure?
At very low pressure in a discharge tube, there are fewer gas atoms present to ionize and produce light. This results in fewer collisions and less emission of visible light, causing the discharge tube to appear dark.
What color does argon produce in a fluorescent tube?
Argon gas by itself does not produce a specific color in a fluorescent tube. It is typically used as an inert gas filler in fluorescent tubes to prevent degradation of the electrodes and enhance the performance of the tube. The color produced in a fluorescent tube is usually due to the phosphor coating on the interior of the tube, which emits visible light when excited by ultraviolet radiation emitted from the tube's gas discharge.

Why gases conduct electricity when pressure is reduced in discharge tube?
When the pressure is reduced in a discharge tube, the mean free path of the gas molecules increases. This allows the gas molecules to gain more energy and move freely, colliding with the charged particles in the discharge tube and facilitating the flow of electric charge. As a result, the gases become partially ionized, creating a conductive path for the electricity.
Why is it necessary to decrease the pressure in the discharge tube to get the cathode rays?
cathode rays can't travel in air
What noble gas is blue?
Krypton is a noble gas that can sometimes exhibit a blue color in certain applications, such as in lighting and laser technology.
Why is hydrogen filled at low pressure in the discharge tube?
because gases do not conduct electricity under normal pressure so at pressure of 0.1-0.001 mmHg with very high potential difference of 5000 to 10000 volts gases conduct electricity and produce fluorescence on the wall of discharge tube and it also avoid the collision of cathode rays with the positive rays
What are the colors of an argon atom?
Argon is a Colorless GasDate of Discovery: 1894Discoverer: Sir William RamsayName Origin: From the Greek word argon(inactive)Uses: LightingObtained From: airBentor, Yinon. Chemical Element.com - Argon. Oct. 26, 2008 .
Which gas is used in discharge tube for the study of cathode rays?
The gas commonly used in discharge tubes for the study of cathode rays is low-pressure neon or argon. These gases allow for the observation of cathode rays because they ionize easily and produce visible light when the cathode rays collide with them. This ionization helps to create observable effects that demonstrate the properties of cathode rays, such as their trajectory and charge.
Why do you use a discharge tube to perform the experiment instead a of light bulb?
It depends on the experiment, of course, but a discharge tube contains ionized atoms, while an incandescent simply has glowing metal. The former is, for most experiments, a lot more interesting.
