Induction Tube Apparatus With 6 Coils, Tube Dimensions (L X D): 1500 X 20 mm, Coil Width: 10 mm, Distance Between Coils: 19 Cm, Due To The Magnet'S Free-Fall Acceleration Caused By Gravity, The Voltage Peaks Increase Proportionally With The Time.
Spectrum Tubes Deuterium, glass tubes approximately 10-1/4in (260mm) long, central capillary portion approximately 3-1/2in to 4in (90-100mm) long with electrodes sealed at both ends and connected to lead wires protected by metal caps.
Spectrum Discharge Tube, Mercury Gas to show spectral lines of pure substances. Tubes approximately 260mm long, central capillary portion approximately 3-1/2 to 4 (90-100mm) long with electrodes sealed at both ends and connected to lead wires protected by metal caps
