Answer:
652.174nm
Explanation:
We need to know that the speed of light never changes. It has a value of 3 × 10^8 m/s.
Given only the frequency, we can find the wavelength by dividing the value of the speed of light by the value of the frequency.
That equals = (3 × 10^8) ÷ ( 4.6 × 10^14) = 0.000000652174 m = 652.174 ÷ 10^-9m = 652.174nm
