We can use the formula: λ = c/f, where λ is the wavelength, c is the speed of light (3.00 × 10^8 m/s), and f is the frequency.
First, we need to convert the frequency from scientific notation to standard notation:
4.62 × 10^14 Hz = 462 × 10^12 Hz = 4.62 × 10^14 Hz
Now, we can plug in the values and solve for λ:
λ = c/f = (3.00 × 10^8 m/s) / (4.62 × 10^14 Hz) = 6.49 × 10^-7 m = 649 nm
Therefore, the wavelength of light is 649 nm, which corresponds to choice C.
