Question: Light of Frequency 8.22 1014 Hz ejects electrons from surface A with a maximum kinetic energy that is 2.00 10-19 J greater than the

Light of Frequency 8.22 ×1014 Hz ejects electrons from surface A with a maximum kinetic energy that is 2.00 × 10-19 J greater than the maximum kinetic energy of electrons ejected from surface B.
(a) If the frequency of the light is increased, does the difference in maximum kinetic energy observed from the two surfaces increase, decrease, or stay the same? Explain.
(b) Calculate the difference in work function for these two surfaces?
