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)

WebRecall that E=hf. The plot is E vs f, but E is given in eV so has to be multiplied by the charge of the electron (1.602E-19 C) to be converted to Joules. This problem has been solved! … WebThe gradient of the graph = E/f = h (Planck’s constant) The line will cross the y axis (c in the straight line equation) -work function; ... Remember: Since E = hf then when E = work function (i.e. the photon has just enough energy to release a photo-electron) then you can rearrange to find threshold frequency. cwitw
