Asked by John
Light with a frequency of 4.32 × 1015 Hz strikes a metal surface and ejects electrons that have a maximum kinetic energy of 5.8 eV. What is the work function (in eV) of the metal?

figure the energy in each photon
energy=PlancksConstatn*(frequency.
work function=photonenergy-kemax
energy=PlancksConstatn*(frequency.
work function=photonenergy-kemax
