(c) The kinetic energy, Kr, of electrons emitted from a metal surface after irradiation with UV light of wavelength A is given by: hc K₁ = π where h is Planck's constant (6.626 x 10-4 Js), c is the speed of light in a vacuum (2.99 x 10 m s¹), and is the work function of the metal surface. In a specific experiment, light with a wavelength of 266 nm was used to irradiate a cadmium (Cd) metal surface. (1) Calculate the photon energy of the light used in the experiment, in Joules. (II) The work function for cadmium is 4.08 eV. Calculate the kinetic energy of the emitted electrons. (Note: 1 eV = 1.60 x 10-19 J.)
