Anode and Cathode

Anode and Cathode

How are the cathode rays produced?

  1. Thermionic emission is used to produce a continuous supply of electrons. These electrons can be made to move at high speed in a vacuum tube as shown in Figure.

How are the anode rays produced?

The pressure in the tube is decreased, it was observed that in addition to cathode rays, a new kind of rays are also found which came through the perforations (holes) of the cathode. These rays travelled in opposite direction of the cathode rays and passed through the holes of the cathode and struck the other end of the discharge tube.
