A laser emits a single, \( 2.0 \mathrm{~ms} \) pulse of light that has a frequency of \( 2.83 \times 10^{11} \mathrm{~Hz} \) and a total power of \( 75000 \mathrm{~W} \). How many photons are in the pulse?
(A) \( 8.0 \times 10^{23} \)
(B) \( 2.4 \times 10^{25} \)
(C) \( 1.6 \times 10^{24} \)
(D) \( 3.2 \times 10^{25} \)
