Photoelectric Effect Calculator
Calculate kinetic energy, stopping potential, and threshold values for the photoelectric effect
Common work functions: Cesium (2.1 eV), Sodium (2.3 eV), Aluminum (4.1 eV), Copper (4.7 eV), Gold (5.1 eV)
Formulas Used
Einstein's equation: KE_max = hf - φ = E_photon - φ
Stopping potential: V_s = KE_max / e
Threshold frequency: f_0 = φ / h
