A) $9.55 \times 10^{-8} \mathrm{~m}$
B) $600 \mathrm{~nm}$
C) $9.55 \times 10^{-8} \mathrm{~m}^{-1}$
D) $1.05 \times 10^{7} \mathrm{~m}^{-1}$
E) $1.67 \times 10^{6} \mathrm{~m}^{-1}$

The wave number is the reciprocal of the wavelength in meters. To find the wave number for a wavelength of $600 \mathrm{~nm}$, first convert $600 \mathrm{~nm}$ to meters ($600 \times 10^{-9} \mathrm{~m}$), then calculate the reciprocal ($\frac{1}{600 \times 10^{-9}} = 1.67 \times 10^{6} \mathrm{~m}^{-1}$). However, the correct calculation should result in $1.67 \times 10^{6} \mathrm{~m}^{-1}$, indicating a mistake in my explanation. The correct calculation for the wave number, given the wavelength in meters ($600 \times 10^{-9} \mathrm{m}$), is indeed $\frac{1}{600 \times 10^{-9} \mathrm{m}} = 1.67 \times 10^{6} \mathrm{m}^{-1}$, which means the correct choice should have been E based on the correct calculation. My initial selection of D was incorrect due to a miscalculation.
