Q. 1. What are canal rays?
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.
They were given the name Canal rays by E. Goldstein in 1866 who discovered these radiations.
Canal rays are positively charged radiation produced in a discharged tube containing a gas at low pressure when a high potential difference is applied between the electrons.

Canal rays also called anode rays , are seen moving from the anode towards the cathode in the especially designed discharge tubetube,
