Calculate the wavenumber (\( \bar{\nu} \)) of yellow light emitted from a sodium lamp having a wavelength \( (\lambda) \) of \( 580 \text{ nm} \).

1. \( 1.72 \times 10^6 \text{ m}^{-1} \)
2. \( 5.80 \times 10^5 \text{ m}^{-1} \)
3. \( 1.72 \times 10^4 \text{ cm}^{-1} \)
4. \( 3.44 \times 10^6 \text{ m}^{-1} \)
