Cathode Ray Tube
Product Code : JL-LE-10497
The Cathode Ray Tube (SKU JL-LE-10497, Cat. No. JSS-065/023) is an evacuated glass tube coated with phosphor, with a negative cathode and a positive anode. When a high voltage is applied, a cathode ray travels from cathode to anode and makes the phosphor glow, showing the ray. The tube demonstrates that electrons cannot pass through a metal screen and the cathode-ray deflection effect.
