Q)

Yellow light emitted from a sodium lamp has a wavelength $(\lambda)$ of 580 nm. Calculate thefrequency $(ν)$ and wave number of the yellow light.

$\begin{array}{1 1} (a) \;V = 5.17 \times 10^{14} s^{-1} , \bar{V} = 1.72 \times 10^6 m^{-1} \\ (b) V = 4.17 \times 10^{14}s^{-1} , \bar{V} = 2.72 \times 10^6 m^{-1} \\ (c) \;V = 3.17 \times 10^{14}s^{-1} , \bar{V} = 1.72 \times 10^6 m^{-1} \\ (d) \;V = 5.17 \times 10^{14}s^{-1} , \bar{V} = 2.72x10^6 m^{-1} \end{array} $
