WebCathode rays in a Crookes tube are seen to travel in straight lines by casting a sharp shadow of a Maltese cross on fluorescing glass. They can also be deflected by magnetic fields, as seen by the distortion of the shadow. Ionization in the base (between the anode and main part of the tube) gives a faint purple glow.

WebCathode Ray Experiment. J.J. Thomson, a scientist, began working with cathode ray tubes in the late 1800s. Thomson used two opposingly charged electric plates around the cathode ray to test the particles' characteristics. The cathode ray was redirected away from the negatively charged plate and towards the positively charged plate. Procedure

WebA cathode made of a wire filament heated red hot by a separate current passing through it would release electrons into the tube by a process called thermionic emission.
