SUMMARY
The threshold frequency for a calcium surface with a work function of 3.33 eV is calculated using the formula f = W/h. The correct conversion of the work function from electron volts to joules is W = 3.33 eV * 1.6 x 10^-19 J/eV, resulting in W = 5.33 x 10^-19 J. Using Planck's constant h = 6.63 x 10^-34 J·s, the threshold frequency is f = 5.02 x 10^14 Hz. The initial calculation of 8.04 x 10^14 Hz was incorrect due to a miscalculation, but the final confirmation shows the book's answer was erroneous, validating the user's calculation.
