Light of wavelength 430. nm is incident on a metal surface withawork function of 2.14 eV.
(a) Calculate the energy of a photon with thiswavelength.
(b) Will photoelectrons be emitted from the metal undertheseconditions (yes or no)? Briefly explain youranswer.
(Look at the photoelectricequation.What must be the sign of the kinetic energy?)
