The momentum of a photon is related to its energy by:
$p = \frac{E}{c}$
Substituting the given values:
$p = \frac{4\cdot8 \times 10^{-19}\text{ J}}{3 \times 10^{8}\text{ m s}^{-1}} = 1\cdot6 \times 10^{-27}\text{ kg m s}^{-1}$
Final answer: 1.6 \times 10^{-27} kg m s^-1
Final answer: 1.6 \times 10^{-27} kg m s^-1
