We can use the formula:
c = λν
where c is the speed of light (3.00 x 10^8 m/s), λ is the wavelength, and ν is the frequency.
First, we need to convert the frequency to Hz:
4.74 x 10^14 Hz
Next, we can rearrange the formula and solve for λ:
λ = c/ν
λ = (3.00 x 10^8 m/s)/(4.74 x 10^14 Hz) = 6.33 x 10^-7 m
Finally, we convert meters to nanometers:
λ = 633 nm
Therefore, the answer is A) 633 nm.
