Photoelectric effect 3.5 / 5 based on 2 ratings ? PhysicsWavesQuantum physicsASAll boards Created by: ChloeGoslingCreated on: 04-01-13 11:56 Define photoelectric effect When a photon strikes a metal surface and if it meets the threshold frequency then an electron is emitted from the surface of the metal.e 1 of 6 Define work function The minimum energy required to remove an electron from the surface of a metal. 2 of 6 Photoelectric effect equation EKmax = hf - φ Maximum kinetic energy = plancks constant X (times) frequency - (minus) work function 3 of 6 y=mx+c for e=hf-φ y axis equals maximum kinetic energy,gradient is plancks constant, x axis is frequency and negative work function is the y intercept 4 of 6 What is threshold frequency The lowest frequency of electromagnetic radiation/photons that will result in the emission of Photoelectrons. 5 of 6 Threshold frequency equation φ=hfo (fo is threshold frequency, h is plancks constant, φ is work function) 6 of 6
