Answer / Solution

Canal rays are positively charged radiations that can pass through perforated cathode plate. These rays consist of positively charged particles known as protons. Or we also say that Canal rays are the positively charged radiations which consist of positively charged particles of atoms, they can pass through the perforated ( pierced ) cathode and then travel towards another cathode in a gas discharge tube.

The anode rays produced at the anode of the discharge tube are called canal rays because they pass through the holes of the cathode.

The two postulates of J.J. Thomsons Model are 

  • The negative and positive charges are equal in magnitude.
  • Atom consists of positively charged sphere and electrons are embedded in it.
