Question

explain discharge tube or cathode ray experiment
​

Answer 1

Answer:

In discharge tube experiment, at low pressure and at very high voltage, an electric current is passed. Due to passage of electric current, a stream of rays is passed in the tube originating from cathode. These rays are called "CATHODE RAYS". These rays originate from cathode.

Answer 2

Discharge tube is also called "CROOCK TUBE". It is made of a glass tube which consists of two metallic plates. One plate is connected to positive terminal of high voltage power supply and the other to negative terminal. The plate connected to the positive terminal is called "ANODE" the other connected to negative terminal is called "CATHODE". The tube is filled with any gas.

EXPERIMENT

In discharge tube experiment, at low pressure and at very high voltage, an electric current is passed. Due to passage of electric current, a stream of rays is passed in the tube originating from cathode. These rays are called "CATHODE RAYS".

PROPERTIES OF CATHODE RAYS

These rays originate from cathode.
Cathode rays travel in straight line.
Cathode rays carry negative charge.
Cathode rays are deflected by electric field.
Cathode rays are deflected by magnetic field.
These rays consist of material particles.
The ratio e / m of these particles was 1.76 x 108 col / gm.
Cathode rays consist of "electron".
The rays, upon striking glass or certain other materials, cause them to glow.
