Recreate the Nobel Prize-winning experiment that proved light quantization. Shine monochromatic light (200 nm UV to 750 nm Red) onto photocathode metals, adjust retarding stopping voltage, and measure maximum photoelectron kinetic energy.
Interactive Experiment Guide
Start with fundamental scientific principles, launch the simulation, and verify mathematical predictions against real-time outcomes.
Scientific Foundation
The photoelectric effect demonstrates the particle nature of light. When photons strike a metal surface, their energy (E = hf) is transferred in single quanta to liberate electrons above the work function threshold.
Interactive Simulation Flow
Launch the simulation workspace, adjust parameters in real time, and observe the immediate response in the telemetry and graphical indicator loops.
Frequently Asked Questions
Einstein's equation states that the maximum kinetic energy (K_max) of an emitted photoelectron equals the incident photon energy (hf) minus the metal's work function (Φ): K_max = hf - Φ = e·Vs.
