Question

What color is produced by protons in the cathode ray tube?​

Answer 1

The anode (positive terminal) is in the base of the tube at bottom. Cathode rays travel from the cathode at the rear of the tube, striking the glass front, making it glow green by fluorescence. A metal cross in the tube casts a shadow, demonstrating that the rays travel in straight lines.
