When light of wavelength 310 nm is incident on a metal surface, electrons are ejected with a kinetic energy of 1.0 eV. a. What is the work function (binding energy) of this metal (in eV)? b. What is the cutoff wavelength of light (in nm) that can eject electrons? Will photons with wavelength 544 nm eject electrons? Explain your reasoning. c. Determine the wavelength of light (in nm) that should be used to double the kinetic energy of the electrons ejected from this surface.
