A typical laser used in introductory physics laboratories produces a continuous beam of light about 1.0 mm in diameter. The average power of such a laser is 0.75 mW. What are
(a) The average intensity,
(b) The peak intensity,
(c) The average energy density of this beam?
(d) If the beam is reflected from a mirror, what is the maximum force the laser beam can exert on it?
(e) Describe the orientation of the laser beam relative to the mirror for the case of maximum force.
