The Photoelectric Effect

Albert Einstein won the Nobel Prize for explaining how light behaves as particles (photons).

Intensity: Increases the number of photons (and thus the current).
Wavelength: Decreases the energy of each photon ($E = hf$).
Work Function (Φ): The binding energy required to eject an electron.
