1. Light of wavelength 375 nm is incident on a metal surface, and it is observed that electrons leave the surface with a maximum kinetic energy of 1.8 eV. What is the work function of this metal? What is the maximum kinetic energy of the electrons if light of wavelength 410 nm is used? What is the longest wavelength of light that will cause electrons to be emitted from this surface? > Gauth
