Understanding the Franck-Hertz Experiment: Causes of Current Drop
2016年9月2日 · In summary, the Franck-Hertz experiment involves bombarding mercury atoms with electrons and observing a sudden change in current when the electrons reach a specific threshold energy. This suggests that the mercury atoms can only accept energy at certain points, corresponding to a strong emission line in the ultraviolet spectrum at 254 nm.
Franck-Hertz (my head) Experiment - Physics Forums
2008年4月10日 · My questions are about the classic Franck-Hertz experiment where electrons are given energy by an accelerating voltage. These collide with mercury atoms, raising their internal energy. The electrons are then left with insufficient energy to overcome the retarding voltage of a collector plate...
Why are the peaks in the Franck-Hertz experiment broad?
2015年11月22日 · The broadness of the peaks in the Franck-Hertz experiment allows for the determination of the energy levels of the atoms in the gas being studied. By analyzing the width and spacing of the peaks, scientists can gain valuable insights into the quantum mechanical properties of the gas and its constituent atoms.
Does voltage affect the current in the Franck-Hertz experiment?
2015年11月11日 · The Franck-Hertz experiment shows that as the voltage (KE of the electrons) increase, the current/energy of the electron increases up to 4.9v at which point it drops due to the non elastic collision. this happens at intervals of 4.9v. assume that the current at 6v was measured to be X
Why is the first peak in the Franck-Hertz experiment longer than …
2022年4月13日 · The Franck-Hertz experiment demonstrates the quantization of energy levels by showing that the electrons can only be excited to discrete energy levels in the gas atoms. This is seen in the distinct peaks in the current-voltage curve, which correspond to the minimum energy required to excite the atoms to higher energy levels.
