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?

Show all work, use additional paper if necessary.
