(d) The work function for Caesium is 2.1 eV. (i) Calculate the
maximum wavelength of light that will cause photoelectrons to be
emitted from the metal. [3 marks] (ii) Calculate the maximum
kinetic energy and the speed of ejected photoelectrons when light
of wavelength 400 nm illuminates the metal’s surface. [4 marks]
