Oops. I goofed in typing in several places. The last part should be:

(d) Energy_of_Photon = hf = 6.63*10^-34 * 2*10^9 J = 1.3*10^-24 J
where h=6.63*10^-34 Js (Plank's constant)
This is the energy of a 2.5 MHz photon.
From (a), PV=5.5*10-^18 Js^-1 m^-2
Therefore, number of photons =
(5.5*10^-18 / 1.3*^10^-24) = 4.2*10^6 m^-2 s^-1

Hmm... I have no idea where the "2.5 MHz" came from or the strange
units for the "number of photons".
