Raise the voltage and watch the collector current rise, then drop, again and again. The spacing between drops is mercury's excitation energy.
Bring this to your lab →Bring the mercury or neon tube to operating temperature with the built-in heater control.
Raise the accelerating voltage while the unit records the collector current at 0.1 V resolution.
Measure the spacing between current peaks to find the atom's excitation energy.
Typical Franck-Hertz curve: current peaks spaced about 4.9 V apart for mercury (illustrative).
Yes. Units supplied through American Scientific are adapted for 110V/60Hz and supported in the U.S., including warranty and replacement parts.
Tell us about your lab in the form above and we'll put together a complete, ready-to-teach configuration, so nothing is missing on day one.
Often, yes. Many institutions fund PHYWE equipment through NSF, Title IV and CTE programs, and our team can help you find and apply for the right opportunity.
