E hf graph

WebThe energy of a photon is directly proportional to its frequency. This gives rise to this equation: \ [E=hf\] \ (E\) is the energy of the photon \ (h\) is Planck's constant, \ … Webequations. 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)
