Einstein and Millikan described the photoelectric effect using a formula (in contemporary notation) that relates the maximum kinetic energy ( Kmax) of the photoelectrons to the frequency of the absorbed photons ( f) and the threshold frequency ( f0) of the photoemissive surface. Kmax = h ( f − f0) WebThe energy (hf) of the photon is given by: ΔE = hf = E 2 - E 1. Where: E 1 = Energy of the higher level (J) E 2 = Energy of the lower level (J) h = Planck’s constant (J s) f = Frequency of photon (Hz) Using the wave equation, the wavelength of the emitted, or absorbed, radiation can be related to the energy difference by the equation: headings helicopters
