A clean cobalt surface is illuminated by ultraviolet light. Nophotoelectrons are ejected until the wavelength of the incident UVlight falls below 318 nm.
(a) What is the work function (in electron-volts) of themetal?
......eV
(b) What is the maximum kinetic energy for electrons ejected byincident light of wavelength 132 nm?
.....eV
