An argon ion laser puts out 6.0 WW of continuous powerat a wavelength of 532 nm. The diameter of the laserbeam is 5.7 mm.
If the laser is pointed toward a pinhole with a diameter of1.1 mmmm, how many photons travel through the pinhole persecond? Assume that the light intensity is equally distributedthroughout the entire cross-sectional area of thebeam. (1 WW = 1 J/sJ/s)
Express your answer using two significantfigures.
