•48 A high-powered laser beam (A = 600 nm) with a beam diam- eter of 12 cm is aimed at the Moon, 3.8 x 10° km distant. The beam spreads only because of diffraction. The angular location of the edge of the central diffraction disk (see Eq. 36-12) is given by 1.22A sin 0 where d is the diameter of the beam aperture. What is the diameter of the central diffraction disk on the Moon's surface?
