Why is it necessary to decrease pressure in the discharge tube to get cathod rays?
why it is necessary to decrease the pressure in the discharge tubbe 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
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.
What type of electrode is a cold cathode?
Cold cathode is a cathode, an electrode that emits electrons, which is not electrically heated by an element. Cold cathodes are used in gas discharge lamps such as neon lamps and discharge tubes.
What do cathode produce on the walls of the discharge tube?
greenish glow or fluorescence
Why deflection is necessary in cathode ray tube?
It is not necessary in a cathode ray tube, it is a side effect and is needed in the calculations to ensure that there are no errors.
What the factors that affect the preferential discharge of ions at the anode and the cathode?
how am i suposed to answer it if i am asking wat it is
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 is an Aston dark space?
An Aston dark space is a dark space in a glow discharge which is adjacent to the cathode.
Why cathode dark space is dark?
The cathode dark space is dark because it contains very few electrons and ions, so there are not enough collisions happening to produce visible light. The low electron density in this region prevents the formation of plasma, which is necessary for light emission. As a result, the cathode dark space appears dark compared to other regions in the discharge tube.
What A low pressure gas filled glass tube which generates a glowing beam between cathode and anode?
Cathode ray.
How is Faraday's dark space created?
Faraday's dark space is created in a gas discharge tube when electrons gain enough energy to collide with gas atoms, causing them to emit light. The dark space is a region near the cathode where electrons lose energy due to collision with gas atoms, causing a decrease in electron density and subsequent decrease in light emission.
