Compute the minimum angular spread of the beam

Reference no: EM13690551

Solve the all parts 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 2.53 m diameter beam of 500 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?

Please clarify the equations and steps are used to get the answer. Thank you!
