Cathode with holesA perforated cathode is a cathode with holes1. It is used in the discovery of anode rays because it allows for the passage of particles from the cathode to the anode, which allows for the observation and study of the anode rays2. If the cathode has a perforated surface, some of the ions will pass through the holes and move towards the anode, forming canal rays3. Cathodes are negatively charged particles, and perforated cathodes are plates that have minute pores in them4.Learn more:✕This summary was generated using AI based on multiple online sources. To view the original source information, use the "Learn more" links.Perforated cathode: Perforated cathode means cathode with holes. In production of anode rays, a perforated cathode ray tube is used which is pierced with holes through which anode rays passed and form red spot behind the cathode because of strike between rays and wall of discharge tube. Through these holes, anode rays move towards cathode.www.meritnation.com/ask-answer/question/what-is …A perforated cathode is used in the discovery of anode rays because it allows for the passage of particles from the cathode to the anode.

Aug 16, 2022 · A perforated cathode is used in the discovery of anode rays because it allows the anode rays to pass through and be observed. This is because the holes in the cathode act as a pathway for the anode rays to travel through, making it easier to detect and study them.

Anode ray - Wikipedia
Goldstein used a gas-discharge tube which had a perforated cathode. When an electrical potential of several thousand volts is applied between the cathode and anode, faint luminous "rays" are seen extending from the holes in the back of the cathode. These rays are beams of particles moving in a direction opposite to the "cathode rays", which are streams of electrons which move toward the anode. Goldstein called these positive rays Kanalstrahlen, "channel rays", or "canal r…
