Calculate the mass of a photon of sodium light with a wavelength of \( 589 \text{ nm} \) (\( c = 3 \times 10^8 \text{ m s}^{-1} \), \( h = 6.626 \times 10^{-34} \text{ J s} \)).

1. \( 6.22 \times 10^{-34} \text{ kg} \)
2. \( 1.89 \times 10^{-35} \text{ kg} \)
3. \( 3.75 \times 10^{-36} \text{ kg} \)
4. \( 7.42 \times 10^{-30} \text{ kg} \)
