Photoelectric tube + filter set (Premium series)

description

The tube is the main part of a system for experimenting with photoelectricity.

A complex system of its components (SKU: 444471,444470, 444468, 444469, 670) for photoelectric experiments, to illustrate the effect of acceleration voltage and stopping voltage on the strength of the photoelectric current in the flow circuit.

In constructing a graph of the dependence of the stopping voltage on the radiation frequency, one can findPlanck's constant, and the workingfunction(bond energy) of the emitting cathode. The threshold frequencyis also revealed through this relationship.

The composition is precise, the error is relatively small.
