ANS: What is positive column in electrode tubes

Each of the electrodes is covered by a velvety glow known, respectively, as the cathode and anode glow. A comparatively dark space near the cathode is called the Crookes dark space. Near it is a short region of light known as the negative glow; this being followed by another darker portion designated the Faraday dark space. The major portion of the tube is filled with a striated series of bright and dark regions called the positive column.
