Monochromatic light with a wavelength of 177.5 nm, shines on a metal plate and ejects electrons. The electrons are observed to leave the metal with a kinetic energy of 3 eV. (a) Calculate the energy of the light in eV. (b) Calculate the momentum carried by the photon. (c) Calculate the work function of the metal. (d) Calculate the momentum of the electrons. (The mass of an electron is 9.11 × 10^-31kg.)
