Correct Option: C
Explanation: Using the formula frequency = speed of light/wavelength, we can calculate the frequency. The speed of light in a vacuum is approximately 3 × 108 m/s. Converting the wavelength from nm to metres (500 nm = 500 × 10-9 m), we get frequency = (3 × 108 m/s) / (500 × 10-9 m) = 6 × 1014 Hz.
