SUMMARY
The correct frequency of red light in air, given a wavelength of 816 nm, can be calculated using the equation F = c / wavelength, where c is the speed of light at 3 x 108 m/s. The wavelength must be converted accurately to meters, which is 816 nm = 816 x 10-9 m or 8.16 x 10-7 m. Using the correct conversion, the frequency can be determined as approximately 3.68 x 1014 Hz.
