An argon ion laser puts out 4.8 W of continuous power at a of 532 nm. The diameter of the laser beam is wavelength 5.6 mm. If the laser is pointed toward a pinhole with a diameter of 1.2 mm, how many photons travel through the pinhole per second? Assume that the light intensity is equally distributed throughout the entire cross-sectional area of the beam. (1 W1J/s) Express your answer using two significant figures. N= IVE ΑΣΦ 4 ? photons/s
