The apparatus consists of a glass bulb with a fluorescent-coated inner wall for observing the path of cathode rays.
It is fitted with two terminals: a cathode (negative terminal) and an anode (positive terminal).
A metal cross is positioned inside the tube to demonstrate the shadow effect produced by cathode rays.
When a suitable voltage is applied across the terminals, cathode rays travel from the cathode toward the rear of the tube and strike the fluorescent coating, producing a visible glow.
The metal cross casts a distinct shadow on the fluorescent surface, demonstrating that cathode rays travel in straight lines.
A magnetic field can be applied through the neck of the tube to deflect the cathode rays upward, causing the shadow to shift accordingly.
Reversing the magnetic field changes the direction of deflection, causing the rays and the resulting shadow to move downward.
