# An argon ion laser puts out 6.0 W of continuous power at a wavelength of 532 nm. The diameter of the laser beam is 5.0 mm . If the laser is pointed toward a pinhole with a diameter of 1.0 mm , how many photons will travel through the pinhole per second? Assume that the light intensity is equally distributed throughout the entire cross-sectional area of the beam. (1 W = 1 J/s)
