Why were anode rays also called as 'canal rays'?

Open in App
Solution

  • The anode rays produced at the anode of the discharge tube are called canal rays because they pass through the holes of the cathode.
  • Anode Rays are called the canal rays as the cathode used is perforated and the anode rays pass through the holes or canals of The cathode opposite to the anode.
  • Anode rays consist of positive alpha charge. So they tilt next to perforated cathode. Perforated cathode consists of negative charge. Perforated cathode pass through the anode rays. They pass next by canals or holes which produce fluorescence. So, they pass with producing fluorescence. That's why Anode rays are known as canal rays.
