A particular photocell uses a lithium cathode. Lithium has a threshold wavelength of 423 nm.
a. Find the work function of lithium in eV.
b. If ultraviolet radiation with a wavelength of 352 nm falls on the
lithium, will the cathode discharge electrons? If so, what is the
maximum energy of the ejected electrons in eV?
