Solve the each part of following question given below:
Question: A telescope can be used to enlarge the diameter of a laser beam and limit diffraction spreading. The laser beam is sent through the telescope in opposite the normal direction and can then be projected onto a satellite or the moon.
Question I: If this is done with the Mount Wilson telescope, producing a 2.54 m diameter beam of 580 nm light, what is the minimum angular spread of the beam?
Question II: Neglecting atmospheric effects, what is the size of the spot this beam would make on the moon?
