A beam of white light (containing frequencies ranging from 4.00 × 1014 Hz to 7.90 × 1014 Hz) is incident on a sodium surface, which has a work function of 2.28 eV. a. What is the range of frequencies in this beam of light for which electrons are ejected from the sodium? b. What is the maximum kinetic energy of the photoelectrons ejected from the sodium? Answer: (a) From 5.50 × 1014 Hz to 7.90 × 1014 Hz (b)...
