About This Product
Electrons passing through a polycrystalline graphite lattice produce diffraction rings on the fluorescent screen, showing their wave nature. From the radii of the rings and the lattice plane spacing of graphite, students can determine the wavelength as a function of anode voltage and confirm de Broglie's hypothesis. This is a D range tube with its connections fixed on the tube, so it is not interchangeable with the S range, which has connections on the stand. The Electron Diffraction Tube D is offered to export buyers in Trinidad and Tobago, Poland, Latvia, Mali, Saint Vincent and the Grenadines and Palestine.
Frequently Asked Questions
What is the difference between the D and S ranges?
D range tubes have their connections fixed on the tube, while the newer S range has connections on the stand. The two ranges are not interchangeable.
What anode voltage does the tube take?
The maximum anode voltage is 5 kV, with an anode current of approx. 0.1 mA at 4 kV. The maximum filament voltage is 6.3 V AC.
What can be measured with the tube?
The wavelength as a function of anode voltage, from the radii of the diffraction rings and the lattice plane spacing of graphite, which also confirms de Broglie's hypothesis.
