Quizplus · Accepted Answer

The energy of a photon can be calculated using the equation E=hf, where h is Planck's constant and f is the frequency of the light. Rearranging this equation gives f=E/h. 
Substituting the given values, we get f = (3.37 × 10^-19 J) / (6.63 × 10^-34 J·s) 
= 5.09 × 10^14 s^-1, which is answer choice C.
