SUMMARY
The Franck-Hertz experiment for neon involves observing how energy is transferred from electrons as a result of inelastic collision while passing through neon gas. The transfer of energy occurs in discrete steps corresponding to the excitement by such collision of distinct energy level transitions in the neon atoms. The excited atoms then emit visible light.

EXPERIMENT PROCEDURE
• Measure target current I as
a function of the voltage U
between cathode and grid.
• Compare the distribution of current
maxima with the excitation
energies of neon atoms.
• Observe the light emitted by the
excited neon atoms.
• Determine the number of lightemitting
levels for various accelerating
voltages.
