Assume it has uniform intensity a) What is the total power that shines into the pupil of an eye with a diameter of 3.0 mm if it is completely illuminated by the laser shining at normal incidence? b) What distance would the pupil have to be from a 100W light bulb for this same total power to be received? (Assume normal incidence.)
