A laser beam aimed from the earth is swept across the face of the moon. a. If the beam is rotated at an angular velocity of 1.55*10^-3 rad/s , at what speed does the laser light move across the moon's surface? (See Appendix E in the textbook for the moon's orbital radius.) b. If the diameter of the laser spot on the moon is 6.25 , what is the angle of divergence of the laser beam?
