We can use the formula c = λv where c is the speed of light (which is constant at 3.00 × 10^8 m/s), λ is the wavelength of light, and v is the frequency of light. First, we need to convert the frequency given in the problem from scientific notation to standard notation: 4.62 × 10^14 Hz = 462 × 10^12 Hz = 4.62 × 10^14 Hz. Then we can plug in the values and solve for λ:

c = λv
λ = c/v
λ = (3.00 × 10^8 m/s)/(4.62 × 10^14 Hz)
λ = 6.49 × 10^-7 m = 649 nm

Therefore, the correct answer is B.
