A 480 nm laser beam is incident on two different metallic surfaces, one made of sodium (Na), the other of magnesium (Mg). If the respective work functions of these metals are 2.66 eV and 3.66 eV, will electrons be ejected by the 480 nm photons? If so, calculate the maximum KE the photoelectrons can have.
