Can you answer question 1 part a?

Consider a laser pen. Construct a problem in which youcalculate the number of photons per second emitted by thepen. Among the things to be considered are the laser pen’swavelength and power output. Your instructor may also wishfor you to determine the minimum diffraction spreading in thebeam and the number of photons per square centimeter thepen can project at some large distance. In this latter case,you will also need to consider the output size of the laserbeam, the distance to the object being illuminated, and anyabsorption or scattering along the way.
