Can someone please help solve this problem and show their work? Thanks!

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: lf this is done with the Hale telescope, producing a 5.08 m diameter beam of 653 nm light, what is the minimum angular spread of the beam? Neglecting atmospheric effects, what is the size of the spot this beam would make on the Moon, assuming a lunar distance of 3.84 times 10^8 m? Incorrect. Remember that the beam was already 5.08 m wide before being widened by diffraction.

Explanation / Answer

Assuming if angle is correct

Angle=size on moon/ distance from moon

So size on moon =angle*distance from moon

Size=59.9 m
