A photon with frequency 9.996 x 10^14 Hz strikes a slab of lead and is absorbed without freeing an electron. a) If the frequency of that photon is the threshold frequency for lead, calculate the work function for lead. Express your answer in eV. b) Assume a photon of wavelength 200 nm strikes the lead, freeing an electron. Calculate the maximum kinetic energy (in Joules) of the liberated electron. c) Calculate the de Broglie wavelength of the emitted electron. You...
