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.
What else can I help you with?
Are anode rays emitted from anode?
There are no rays assign as anode rays (cathode rays are there in a discharge tube) but during discharge tube experiment positive rays are observed which are generated by decomposition of gaseous molecules present in the tube. X-rays are produced by striking of cathode rays with anode so x-rays may be called as anode rays.
What are the consequences of discharge tube?
Ddischarge tube led to the discovery of Cathode rays (electrons) and Positive rays (protons) so this discovery of cathode rays and positive rays can be considered as conse quences of discharge tube.
Why anode rays also known as canal rays?
Anode rays are also known as canal rays because they were discovered to be positively charged particles produced in a cathode tube when the cathode rays strike a gas at low pressure. The particles travel in the opposite direction of cathode rays and move towards the anode or positive electrode, hence the name "anode rays."
Who discovered gas discharge tube?
Johann Wilhelm Hittorf, a German physicist, is credited with discovering the gas discharge tube in the mid-19th century. His experiments with cathode rays in partially evacuated tubes laid the foundation for the development of early gas discharge tubes.
What following piece of equipment was used by jj Thomson to find electrons?
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.
Why it is necessary to decrease the pressure in discharge tube to get cathode rays?

Why is it necessary to decrease the pressure in the discharge tube to get the cathode rays?
cathode rays can't travel in air

Where does the thermionic emission occur in cathode rays tube?
Thermionic emission occurs at the cathode in a cathode ray tube, which is a vacuum tube that generates electron beams. When the cathode is heated, electrons are emitted and accelerated towards the anode, leading to the generation of cathode rays within the tube.
How is the formation of anode and cathode rays?
Goldstein used a gas discharge tube which had a perforated cathode. When a high electrical potential of several thousand volts is applied between the cathode and anode, faint luminous "rays" are seen extending from the holes in the back of the cathode. These rays are beams of particles moving in a direction opposite to the "cathode rays," which are streams of electronswhich move toward the anode. Goldstein called these positive rays Kanalstrahlen, "channel rays" or "canal rays", because they were produced by the holes or channels in the cathode
In cathode ray tube cathode and anode rays travel opposite to each other but they are not neutralized. why?
There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.

Is cathrone rays steams of electron?
yes, cathode rays are streams of electrons
What do cathode produce on the walls of the discharge tube?
greenish glow or fluorescence
