Cathode rays and their 15 properties

Definition of cathode rays:

Cathode rays are the group of fast moving negatively charged particles. These negatively charged particles are electrons. These rays are shot out at a high speed from the cathode of a discharge tube at a pressure below 0.01 mm of mercury.

15 Properties of Cathode rays:

1.       Cathode rays travel in straight lines.

2.       These rays are deflected by electric field. This is obvious because these rays are nothing but electrons.

3.       These rays travel normally from the surface of cathode. Continue reading “Cathode rays and their 15 properties”
