Электровакуумная трубка с натрием Sodium Fluorescent Tube on Furnace WallFor demonstrating the resonant fluorescence of sodium. It can be clearly demonstrated that energy can only be absorbed at a resonant frequency. The frequency of the incident light must coincide exactly with one of the atom's resonant frequencies. It is not possible to sub-divide the quantum energy h x f.When the tube is illuminated with sodium light at approx. 200°C, the entire bulb lights up. The sodium D line can be observed very clearly.When the tube is illuminated with white incandescent light at approx. 240°C, the light of the same wavelength as the D-line is absorbed, and dark lines become visible in the colour spectrum in the spectroscope.The highly evacuated tube, coated with repeatedly distilled sodium and filled with argon, is operated using the heater 8482190.Tube in mm (L x D): 170 x 42Weight: approx. 550 gAdditionally required:8482190 Heater for Franck-Hertz Experiment and Sodium Fluorescence.8472660 Hand-Held Spectroscope with Adjustable SlitLight sources: sodium spectral light or optical lampПодробности уточняйте у менеджеров компании
