• Linear propagation of cathode rays / of electron beams
• Electrostatic charging effects
• Electron deflection by a magnetic field
Experiment description: ..
Straight-line propagation of electrons in the absence of a field can be demonstrated in a Maltese-cross tube by showing how the shadow of the electron beam coincides with the shadow due to a light beam. Any deviation from the straight-line propagation of the beam, due to a magnetic field for example, can be seen since the shadow is then caused to move.
