To find the frequency corresponding to an absorption line at 502 nm, you can use the formula ( f = \frac{c}{\lambda} ), where ( c ) is the speed of light (approximately ( 3 \times 10^8 ) m/s) and ( \lambda ) is the wavelength in meters. First, convert 502 nm to meters: ( 502 , \text{nm} = 502 \times 10^{-9} , \text{m} ). Then, substituting the values gives ( f = \frac{3 \times 10^8 , \text{m/s}}{502 \times 10^{-9} , \text{m}} \approx 5.96 \times 10^{14} , \text{Hz} ).
