9. Consider green light with a wave length of 530 nanometers (nm). a) What is its frequency in Hz? b) What is the energy (in Joules) of a single photon? c) Suppose you shine the green light on metallic sodium with a work function of 2 eV. Will you see ejected electrons? What will be their kinetic energy? (Recall that 1eV is equivalent to 1.6 *10^-19Joules.)
