Gas Discharge Tube, Set of 6 As above, but with a stand to hold all the six tubes and a rotary switch to activate each tube one by one   Deflection Tube To show deflection of cathode rays by a magnet . Horizontal tube is fitted with a fluorescent aluminium plate , the cathode side of which is bent at right angle and is provided with a slit . Cathode rays passing through the slit cast a sharp and bright shadow across the aluminium plate . When a magnet is brought near , the cathode rays deflect sharply.     Rectilinear Propagation of Cathode Rays V-shaped to demostrate cathode rays extend in straight lines perpendicular to cathode disc     Canal Ray Tube To show positive rays. Vertical type , with two fused discs at each end and a perforated cathode in the center through which canal rays pass. The space below the cathode is filled with characteristic glow of cathode rays and the upper portion has canal rays. A magnet brought near the upper portion will repulse the rays, showing the positive nature of the canal rays     Molecular Vibrating Tube Highly evacuated glass tube with mercury & glass beads. Upon heating on a spirit lamp, the glass beads soon start moving in exact resemblance to the Brownian movement. :: TOP :: | Mechanics | Electricity | Magnetism | Sound | Electronics | Electrical Accessories | Vacuum Apparatus | Heat | Electrostatic | Optics | Chemistry | Fiber Models | Microscopes | Corks |
