How discharge tube is different from tube light?
discharge tube can be used for indentifying electrons while tube light cxannot
Fluorescent lamp low pressure mercury vapour?
A fluorescent lamp refers to a low pressure mercury-vapor gas-discharge lamp that uses fluorescence in order to produce visible light. It is also called a fluorescent tube.
State the basic principle of the pressure tube log?
the basic principles of the pressure tube log
Why a tightly fitting cork on a test tube is blown off if the test tube is heated?
The air molecules inside the test tube have a higher mobility when heated (they move around more). The collisions between these air molecules create more pressure on the inside of the test tube (force/area, where the force is the result of the increasing collisons and the area is the internal wall of the test tube.) This may result in the pressure inside of the test tube to be greater than the outside atmospheric pressure on the cork (actually atmospheric pressure on the cork and the frictional force on the cork created by the mouth of the test tube). If the internal pressure becomes greater than the external pressure (plus frictional force) the cork will come loose of the test tube.
What equalize the pressure within the ears?
The Eustachian tube equalizes air pressure in the ears
Why it is necessary to decrease the pressure in discharge tube to get cathode rays?
why it is necessary to decrease the pressure in the discharge tubbe to get cathode rays
Why glow appears in discharge tube?
because excite of gaseous atoms emit photons .
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 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
How discharge tube is different from tube light?
discharge tube can be used for indentifying electrons while tube light cxannot
Why argon is not used in discharge tube even at low pressure?
The question cannot be answered sensibly because argon is used!
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
Why crook tube is called discharge tube?
If it's a *Crookes* tube you're asking about, it's a discharge tube because the applied electrical field causes ionization and a resulting discharge of energy in the form (mostly) of light, depending on the gas or gases in the tube.
Ionization of gas in the discharge tube?
yes
In the Thomson experiment to determine the Specific charge of an electron If the pressure in the discharge tube is made is made as low as nearly zero dose conduction takes place?
In Thomson's experiment the tube used is evacuated i.e. there is vacuum inside.
What is blue gas?
argon is blue in discharge tube
