Structure of Atom
What is the difference in the origin of cathode rays and anode rays?
Cathode rays consist of negatively charged material particles called electrons. These rays deflect towards the positive plate of an electric field. The charge to mass (e/m) for the particles in the nature of the gas taken in the discharge tube.
Anode rays consists of positively charges material particles. These rays deflect towards the negative plate of an electric field.
