Presets
Light ejects electrons from a metal only if each photon carries enough energy — no matter how bright a below-threshold beam is. Einstein explained it with KEmax = hf − φ: energy comes in photon packets of hf, and the work function φ is the escape cost. Below the threshold frequency, nothing happens. This won him the Nobel Prize.

Governing equation
Reading this result: Each photon carries 3.31 eV, above the 2.3 eV work function, so electrons escape with up to 1.01 eV — a brighter beam adds more electrons, not more energy per electron.
