Frequently Asked Questions
Why does brightness not affect electron energy?
Brightness changes how many photons arrive, not how much energy each carries. Electron energy depends on the photon energy, set by wavelength, minus the work function.
What does no emission mean?
If the photon energy is below the work function, no electrons escape no matter how bright the light, so the calculator reports no emission and a stopping voltage of zero.
